MM must be open if you want to install an AddOn. So it wasn't a fault installing the AddOn while MM is running.banquo wrote: ↑Sat May 26, 2018 1:05 pm Hi,
I'm getting an error msg when I try to install this addon in Windows 10 (latest version). When I double-click on the mmip file, MM launches, I choose Install Now in the Product Installation window, and it fails with the error "Discogs Tagger was not installed." Oddly, it was installed and working at one point -- I think I clicked Open after the file DL, while MM was running. But Discogs wasn't showing up as an Option under Auto-Tag from Web, so per other recommendations here, I uninstalled Discogs... and now it won't reinstall. Not sure what else to try.
If you start MM now, do you see that Discogs Tagger is still installed? If so, please try to uninstall it again.
If you try again to install then, what error message you see exactly?
