What i did for this, was to rename the old install dir, recreate it new (empty).
but preserve the config (beyond AppData\local), simply doing an “Upgrade” here of the config.
By that all components the apps used were preserved. Restriction: I normally don’t install them within the IDE but simply use them dynamically from within a program, so a rebuild of the IDE was not needed.
In short, maybe it's better to use a clean install dir.
