Hi @Schrader, Arthur,
Welcome to Microsoft Q&A!
The error code 1625 usually means that there are some policies on your machine block the Installer to install the package.
Please check if there is an anti-virus software or group policy blocking you.
Besides, please check if a required certificate has been revoked. You can follow the instruction below to remove the revoked certificate:
Search Internet Options in Windows search bar > Content > Certificates > Untrusted Publishers > Remove the publisher.
After removing the revoked certificate, please go to Visual Studio Installer and repair the VS installation.
Sincerely,
Anna
