If you have Bluetooth problems after a Windows 10 upgrade or update, see Fix Bluetooth problems in Windows Select and hold or right-click it, and then select Open file location. Select and hold or right-click the program file, select Properties , and then select the Compatibility tab. Here’s what to look for and what each setting does when it’s selected.

Runs the program using settings from an earlier version of Windows. Try this setting if you know the program is designed for or worked with a specific version of Windows. Uses a limited set of colors in the program. Some older programs are designed to use fewer colors. If your program isn’t displayed correctly on a PC with a high-DPI display its features are blurry or are too big or too small , select Change high DPI settings , and then try one of these options in the Properties dialog box:.

In the Program DPI section, select Use this setting to fix scaling problems for this program instead of the one in Settings to use the DPI settings you want to use for this program. Note: This changes the DPI only for the app you’re adjusting. For more info about changing the setting for all apps, see Fix apps that appear blurry. This is the default setting. I open this program — Use the DPI that was set for your main display at the time you open the specific program.

When PCA detects that the DLL failed to load properly, it will applies a compatibility setting that allows Windows to load the latest version of the DLL from the Windows system folder so the app can run properly.

At the end of the first failed run of the app, users will see the PCA dialog that notifies them of the applied setting as below:. On bit version of Windows 8, a new exception was enabled to the message loop callback mechanism. While this exception was first introduced in Windows 7, it was not mandatory to handle this error. In Windows 8, apps that use message loops must handle this new exception. If they do not, they will crash.

Apps designed for older Windows versions may not be aware of this exception, and hence may not handle this error exception properly. After the setting is applied at the end of the run, the user is notified as below. The app will get the mode on the next run, and will be able to avoid this error. Some apps designed for Windows XP and prior assume that they usually run with full administrative privileges.

As a course of normal app behavior, they may try to delete protected non-Windows files either in program files or Windows folders. When the delete operation fails many such apps can crash. PCA detects these apps that fail to delete protected files and crash, and provides a recommendation to the user. As a course of normal app behavior, they may try to modify, delete or write Windows protected files either in program files or Windows folders or Registry keys owned by Windows.

When any of the write, delete or modify operation for a file or a registry key fails many such apps can crash or fail badly.

PCA detects these apps that fail to write to protected Windows files or registry keys, and provides a recommendation to the user when the app quits. As in any of the scenarios, the user can tell PCA that the app ran correctly, or opt out of the recommended settings by clicking the Close button. Lower color modes are now simulated. Many older apps and games designed for Windows XP or before use 8-bit or bit color modes.

With no mitigation, these apps could fail to execute on Windows 8. However, when these apps enumerate or try to use any of the 8-bit or bit color modes for display, PCA immediately identifies the issue and with the help of DWM, ensures that the app will work properly with the simulated color mode. Note that this happens as soon as the app requests the low color modes and is transparent to the user. The user does not have to restart the app to get this mitigation because this fix is always needed to ensure that the app works properly.

Among the common problems that can occur due to this mismatch in settings are clipped UI elements or text and incorrect font size. For more details on the issues, see this link here. PCA will then inform the user about this as shown below:. Some apps depend on Windows features that have been removed since Windows Vista. PCA detects apps when they try to load the missing Windows features, and provides a recommendation to download these components and install them after the app terminates.

If needed, the user can choose to do nothing by clicking Close. However, older apps designed prior to the release of Windows Vista shipped drivers that were not digitally signed. If such an unsigned driver is installed, Windows will not load them. In rare cases, it is possible that Windows will not start if such drivers are marked as boot-time drivers. Some older apps install drivers that are not signed on bit Windows. Any device or app that tries to use this driver may fail or result in a system crash.

To prevent such a scenario, PCA detects apps when they install unsigned drivers, and disables the driver it is marked as a boot-time driver. It also instructs the user to acquire a digitally signed driver for the app to work properly. The message is shown as a result of the installation of the driver, and as a result of the installation of the app. I have the same question Report abuse. Details required :. Cancel Submit.

Compatibility assistant windows 10 free download

 

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Program Compatibility Assistant PCA is a feature in Windows 8 that helps end users to run desktop apps designed for earlier Windows versions.

Windows 8 has great built in app compatibility http://replace.me/24291.txt enables http://replace.me/16598.txt designed for Windows 7 or earlier Windows versions to work great on Windows 8 automatically.

However, there are a small number of apps that can have trouble running without intervention. When a user runs viewer free for 10 64 bit app, PCA tracks the app and identifies any symptoms of certain known compatibility issues in Windows 8.

When it detects any issue symptoms, it provides the user an opportunity to apply a recommended fix that will help run the app better on Windows 8.

PCA tracks apps for a set of known compatibility issues in Windows 8. PCA tracks the issues, identifies the fixes, and provides a dialog to the user with instructions to apply a recommended fix.

The user can decide to apply the recommended fixes, or choose to do nothing and cancel out of the recommendation. If the user cancels out, PCA will no longer track that app. A glossary at the end of the document lists each of the compatibility modes that PCA applies and its description.

For all scenarios listed below, PCA tracks apps for a second time after a fix is applied. If the app continues to fail in the same way even after a compatibility fix is applied, PCA revert the fix. PCA will then permanently stop tracking the specific app that failed.

While PCA tracks many potential issues, not all of the issues will actually cause app продолжить чтение. PCA recommends fixes only in situations where there is a high probability compatibility assistant windows 10 free download the app failure is due to Windows compatibility reasons. The sections below compatibility assistant windows 10 free download on each of the PCA scenarios developed in Windows 8. Each section describes the problem scenario and the recommendations that PCA provides to allow the app to continue working properly on Windows 8.

To learn more about compatibility changes in Windows 8, refer to the other topics in the Windows 8 Compatibility Cookbook. One of the compatibility assistant windows 10 free download common types of app failures occurs during the installation of the app. Older Setup programs compatibility assistant windows 10 free download commonly fail in two ways:. These failure conditions are two of the most common types of compatibility assistant windows 10 free download failures in setup.

PCA, with the help of various other Windows components such as UAC, detects Setup programs at launch and tracks them to the end of the install. In this case, Посмотреть еще recommends a compatibility mode appropriate for the app.

The compatibility mode allows the setup program to run in the Windows mode it was designed for and also ensures that the app runs with administrative privileges. The user, at the end of the failed install, will see a dialog with the PCA compatibility assistant windows 10 free download. One of the more common compatibility failures in app runtime is due to the Windows version check. Many apps, upon launch check the Windows version; if they do not recognize the version, they block themselves even if the app could have run without issues.

If PCA identifies both of these conditions for an app, it will provide a recommendation to the user. PCA will allow the user to re-run the app with compatibility settings. As in any of the scenarios, the user can quickbooks desktop 2021 Compatibility assistant windows 10 free download that the app ran correctly, or opt out of the recommended settings by clicking the close button. An example dialog is provided as below:.

Some apps need administrative privilege to run and execute their functionality. However, older apps generally fail in two ways:. The user will get a UAC prompt when the app re-runs. As in any of the scenarios, the user can choose to re-run with the recommended setting, or opt out of the recommended settings by clicking Close.

Some apps crash due to a well-known memory problem. This causes an immediate crash of the app. While this problem is not due to Windows 8 compatibility changes, it is a relatively common problem seen in a wide variety of apps. PCA tracks this issue to give users a chance to run their app more reliably. So, the function call into the DLL by the app will work, preventing the app from crashing and allowing it to continue to function properly.

When such apps are installed, the app has both an older copy of the DLL in its own folder as well as the latest version compatibility assistant windows 10 free download the DLL that is in the Windows system folders. Since the app is generally not по ссылке of the newer versions of this DLL, it fails to work properly.

When PCA detects that the DLL failed to load properly, it will applies a compatibility setting that allows Windows to load the latest version of the DLL from the Windows system folder so the app can run properly. At the end of the first failed run of the app, users will see the PCA dialog that notifies them of the applied setting compatibility assistant windows 10 free download below:.

Compatibility assistant windows 10 free download bit version of Windows 8, a new exception was enabled to the message loop callback mechanism. While this exception was first introduced in Windows 7, it was not mandatory to handle this error. In Windows 8, apps that use message loops must handle this new exception. If they do not, they will crash. Apps designed for older Windows versions may not be aware of this exception, and нажмите для деталей may not handle this error exception properly.

After the setting is applied at the end of the run, the user is notified as below. The app will get the mode on the next run, and will be able to avoid this error. Нажмите чтобы прочитать больше apps designed for Windows XP and prior assume that they usually run with full administrative privileges. As a course of normal app behavior, they may try to delete protected non-Windows files either in program files or Windows folders. When the delete operation fails many such apps can crash.

PCA detects these apps that fail to delete protected files and crash, and provides a recommendation to the user. As a course of normal app behavior, they may try to modify, windows 10 restore or write Windows protected нажмите чтобы увидеть больше either in program files or Windows folders or Registry keys owned by Windows.

When any of the write, delete or modify operation for a file or a registry key fails many such apps can crash or fail badly. Compatibility assistant windows 10 free download detects these apps that fail to write to protected Windows files compatibility assistant windows 10 free download registry keys, compatibility assistant windows 10 free download provides a recommendation to the user when the app quits.

As in any of the scenarios, the user can tell PCA that the app compatibility assistant windows 10 free download correctly, or opt out of the recommended settings by clicking the Close button.

Lower color modes are now simulated. Many older apps and games designed for Windows XP or before use 8-bit or bit color modes. With no mitigation, these apps could fail to execute on Windows 8. However, when these apps enumerate or try to use any of the 8-bit or bit color modes for display, PCA immediately identifies the issue and with the help of DWM, ensures that the app will work properly with the simulated color mode.

Note that this happens as soon as the app requests the low color modes and is transparent to the user. The user does not have to restart the app to get this mitigation because this fix is always needed to ensure that the app works properly. Among the common problems that can occur due to this mismatch in settings are clipped UI elements or text and incorrect font size.

For more details on the issues, see this link here. PCA will then inform the user about this as shown below:. Some compatibility assistant windows 10 free download depend on Windows features that have been removed since Windows Vista. PCA detects apps when they try to load the missing Windows features, and provides a recommendation to download these components and install them after the app terminates. If needed, the user can choose to do nothing by clicking Close.

However, older apps designed prior to the release of Windows Vista shipped drivers that were not digitally signed. If such an unsigned driver is installed, Windows will not load them.

In rare cases, it is possible that Windows will not start if such drivers are marked as boot-time drivers. Some older apps install drivers that are not signed on bit Windows. Any device or app that tries to use this driver may fail or result in a system crash.

To prevent such a scenario, PCA detects apps when they install unsigned drivers, and disables the driver it is marked as a boot-time driver. It also instructs the user to acquire a digitally signed driver for the app to work properly. The message is shown as a result of the installation of the driver, and as a result of the installation of the app.

If another app installs the same driver, that app will get the same message as well. When an installer fails, PCA helps the installer with various compatibility compatibility assistant windows 10 free download depending on the type of failure.

Once the installer succeeds with compatibility settings, PCA will track the shortcuts that the installer added. This is done to track if compatibility assistant windows 10 free download apps that were installed may also need the compatibility settings applied to their installer.

When a user launches such an app, PCA prompts the user to ask if the app worked properly. Apps http://replace.me/25634.txt launch child programs that need to run as administrators.

This is typically the case when an app tries to launch its updater software to check and install new updates to the app. When apps directly run such child programs, the child program can fail to launch because the app itself did not have administrative privileges, or детальнее на этой странице the child program compatibility assistant windows 10 free download not properly marked for elevation with the UAC manifest.

When the app launches the child app on subsequent runs, the user will see a UAC dialog for the child program. Installers of Windows desktop apps require administrative privileges since they write files, folders, and registry entries to protected system areas. Windows UAC has detection logic to identify when an installer is run, and immediately prompts the user to provide administrative privileges through the UAC dialog.

However, in some cases, this logic will not be able to determine that an app was indeed an installer, and may not get administrative privileges. These are generally custom made installers that do not use well known install technologies such as Windows Installer or Install Shield.

In such cases, PCA detects that the installer failed to write its files. At the end if the failed install, PCA will provide a recommendation to apply compatibility settings. If the user chooses to close, then no setting will be applied. An example PCA dialog is shown below:.

Legacy Control Panel applets that need to run with administrative privilege Control panel applets generally change system settings and need the ability to run ad administrator. When such applets are run, PCA detects them, and at the end of the first run, provides a recommendation to run with administrative settings.
