Error message when updating Studio 2019_corrupt files

Hello all,

I get the error message "Some installation files are corrupt. Please download a fresh copy and retry the installation" when trying to install SDL Trados Studio 2019 SR2 CU7.

I currently have the SR1 Version and it seems that there's also a compatibility issue with my Multiterm (2019 Version).

I tried several times to download a fresh copy, but the problem persists.

Any ideas?

Thank you in advance!
