Before performing this operation, we need to know that, starting from IE10, the IE browser has a built-in Flash Player plug-in customized by Microsoft by default, which exists in the form of Windows system update patches, if you download the Flash Player independent installation package from the Internet, the following error occurs:
Installation error: your Microsoft Internet Explorer browser contains the latest version of built-in Adobe Flash Player. When a new Flash Player version is available, Windpws UPdate will notify you.
To reinstall Flash Player, we need to first uninstall the Flash Player patch in the system, and then reinstall the patch. The method is as follows:

- 32-bit computer
6. Restart the system after installation;
Now the Flash Player reinstallation has been completed. We are opening Youku and randomly entering a video to see if it can be enabled normally. If the problem persists, proceed with the following operations:
Method 2. Fix the Flash Player plug-in
In this solution, you need to manually set the permission for the directory where the Flash Player plug-in is located, so that we do not encounter permission problems when fixing the Flash Player, as follows:
