The solution is as follows:
Cause analysis:
1. The user has insufficient permissions and does not have the permission to write to the Flash Player Registry key.
2. The previously installed flash player is not uninstalled.
Solution:
1. If you have insufficient user permissions, perform the installation test again with the administrator permission.
2. If the flash player has not been uninstalled, uninstall the Adobe flash player in the add/delete program on the control panel, restart the computer, and reinstall it.
3. If the flash player cannot be installed because it is not uninstalled, download the official uninstaller in the attachment and restart the computer for testing. Xitonghe.com
4. If you still cannot install the registry after uninstalling the registry, try to delete the registry key. However, the operation on the registry is risky, therefore, you must back up data before performing the operation. Go to the registry and find the following path:
[HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ ActiveX Compatibility]
Remove the primary key for the {D27CDB6E-AE6D-11CF-96B8-444553540000} item or {D3f97240-C9f4-11CF-BFCr-00A0C90-00A0C90C2BDB} item under it, restart the computer, and then install.
At the same time, this method is also applicable in the XP system. If you encounter a problem that you cannot register when installing Flash, try the solution shared in the previous section. Thank you for reading it!
