Post SSMS21 Extension Not Loading Reply with quote
Doing a trial run for SSMS21 but couldn't get it to work at all. Have tried uninstalling/reinstalling, toggling the register addon but none of them seem to work.

Any help would be greatly appreciated. Thanks

Hi,
I'm getting the exact same errors in the log after an Installation on SMSS 21.6.17.
I've already tried re-registering the add-in via the options. Unfortunately, without success.
Is there a solution?

Thanks.
Best regards
Frankie

It appears SQL Assistant finds SSMS 21 installed, but then it's unable to install the main addon, "SSMS 2025 (21.x) MEF ... REGISTRATION ERROR"
This diagnostic message indicates that something is missing, the diagnostics utility doesn't find all files and registry entries required for SSMS 21 addon.
Do you think you can try unregister/register again while your antivirus is stopped?

On that machine runs a Microsoft Virus & Threat Protection and I have no chance to switch it off. It is managed by the IT department.
Is there any Logfile written when I register that addin? That I can check?
Thanks!
