     To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1.
     Note: There is some performance penalty associated with assembly bind failure logging.
     To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

Check if this path exists on your C drive. The "Packages" folder is used to save VS extensions which VS needs. I'd moved mine to F drive to save space. The error message didn't help me much.

C:\ProgramData\Microsoft\VisualStudio\Packages

If repair doesn't work, you might've moved your VS install and now it won't install anything.

This is because it "might" be finding the VS Installer in a directory OTHER than the standard one. Reinstall the installer itself, then try to install the extension or whatevs
