Hi MichaelHayashi,
- Did you make any changes on your computer prior to this issue?
- What happens when you try to install any update?
- Which uninstaller you are referring to? Do you get any error message when the uninstaller stops working?
Let’s try these steps & check if it helps.
Method 1
You may run system file checker [SFC] scan on the computer which will replace the missing or corrupt files & check if the issue persists.
a. Type cmd in start search box. Right click on cmd in the Program list and then select the option Run as administrator.
Note: If you are prompted for an administrator password or for confirmation, type your password, or click Continue.
b. Type the following command, and then press ENTER:
sfc /scannow
For more information refer this link.
Method 2
You may create a new user account with administrative privilege and check if the issue persists.
If you don’t have any issue in the new User Account, access the link below and follow the steps to fix a corrupted user profile:
