Hi,

1. Is the computer on a domain?

2. Does the issue occur only while using standard user account with User Account Control at maximum?

UAC (User Account Control) - Filevirtualization

The way it works is that when you try to write to a protected zone, such as Program Files, without prompting for administrator rights, you are redirected to a mirror location of the program files folder in the %userprofile% under the folder name VirtualStore, where you have write access. This helps many legacy applications work properly without user intervention.

Method 1:

I would suggest you to refer the link and try to run the Fix it.

Method 2:

Refer the link and check if it helps:

Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs.

For more information about how to back up the registry, refer the link:

I would suggest you to create a new user account and check if the issue persists.

Create a user profile.

If the new user profile resolves the issue, you can fix the corrupt profile and re-install the applications and programs.
