Android Studio “Unable to save plugin settings”

Question

When I opened android studio today, it showed me the following errors:

Answer 1

For my case this seems to be a rights issue. When starting Android Studio with admin rights no problems occur.

Re-enabling the plugins as admin and starting AS again with my default user does not help.

Edit

I updated to the latest canary. With the admin user I've installed AS. I completly removed .AndroidStudio/config, .AndroidStudio/system and .AndroidStudio/plugins beforehand (I use a different location for these files, so I have to replace idea.properties after every installation. While doing this, I've noticed, that they renamed .AndroidStudio to AndroidStudio.2. That gave me the hint to remove those dirs.) After this, I had no problems, regardless of which User ran AS.
