Permission denied error after installing update

When you install or update your SketchUp plugin, it is very important to close all SketchUp windows and restart SketchUp.  Otherwise you may see an error like this when loading:

Error: #<Errno::EACCES: Permission denied @ unlink_internal

If you see this error:

1. Close all SketchUp windows and restart.
2. If that doesn't work, restart your computer.

These steps will fix the error for most users.  If you are still having trouble, you should check if you have a cloud storage app such as Dropbox or Onedrive which might be trying to sync the file.  Or, your anti-virus software might be trying to access the file which could also cause the permission error.

If you are still having problems after trying the above solutions, please submit a request.
