SDL Trados Compatibility and Migration Power Pack Not Work

Hi,

One of the main features I used to use in previous SDL Trados version was the Upgrade Translation Memory function, which I was told was trimmed out of the platform and turned into an App.

I have downloaded the SDL Trados Compatibility and Migration Power Pack and tried several times to install it in my SDL Trados 2021 Pro to no avail. It isn't even listed as one of my Downloaded Apps.

I run SDL Trados Studio 2021 in a Spanish on Windows 10 PRO.

Would you please let me know if it only works on an English setting? If not, what potential problems I should start looking for to have this problem solved?

Thanks!
