Installation of Trados Studio 2019 failed

My PC went wrong, and I recovered the Windows, but all utilities were gone.

When I tried reinstalling Trados Studio 2019, the following message came up:

Setup has detected that the file 'C:\Users\tsnok\AppData\Local\Temp\VSD375A.tmp\DotNetFX472\NDP472-KB4054531-Web.exe' has changed since it was initially published.

Please help me out.
