We are not familiar with this kind of error during the installation.

However, I have a few suggestions that might help:

First, make sure you run the installation as administrator.

If that still doesn’t work, please refer to the following article that might help solving the issue: https://windowsreport.com/fix-windows-10-error-1935/


Please try and update.


Thanks, Yulia,
