Installation error

Good afternoon to all,

I am hoping someone on this forum will be able to help out with my installation issue.

It is a membership bought by my school, not my own.

When trying to install TradosStudio2021SR1, I get the following error:

Checksum error in TradosStudio2021SR1\Modules\TradosStudio.msi
Unexpected end of archive

Some installation files are corrupt.
Please download a fresh copy and retry the installation.

I have tried to refresh the computer as well as reinstall the whole package anew to no avail. What have I done wrong? I can offer any system details you may need.

Thank you very kindly!
