hi b0n3z,
Just to let you know you aren’t alone. (unless someone finds a fix, don’t need a response). We have 4 of these in our environment too (out of about 15 users) where the rct console extension fails to install and we have to use the MSI instead, I haven’t been able to find a fix either. The latest one is on my freshly reimaged machine. (disabling Mcafee didn’t help) MECM 2107(with patch). It was installed fine on my machine before I reimaged it too.
Uninstall, reinstall webview2 (and another extension) without a problem, just won’t install RCT. Even tried copying the files from a working machine to the empty folder in “C:\Program Files (x86)\MECM Console\Extensions\99429045-5ed9-42f0-992b-d73f628e6131\4.8.2109.3303” - same error.

side note, probably unrelated, but finding this in most of the default menus xml’s was interesting (time for an update
)
