This is pretty crude but, on macOS you can use the following in Terminal to enumerate plugin versions:
Code:
find "/Library/Application Support/Avid/Audio/Plug-Ins" -name Info.plist -print -exec /usr/libexec/PlistBuddy -c "Print CFBundleShortVersionString" "{}" \;
For better or worse, it also captures the version of PACE (iLok) against which the plugin was built, which may be useful with the current issue. I'll leave it to someone else to tabulate and prettify the output
