The problem is Sketchup having troubles with special characters such as ‘ç’ in the user profile path. They will need to fix this in a future maintenance release of SketchUp. This Sketchup problem will manifest itself on a lot of plugins from the extension warehouse also.
Currently you can work around as follows:
- create a new user on your computer without any special characters in the name.
- Install and use SketchUp on that users.
- After you have create the new user profile, you may change your user name back to your real name including the ‘ç’. On renaming a user, Windows will NOT change the actual profile paths themselves, so everything keeps working.
I do understand this is not an elegant solution, as you end up with either 2 user accounts and having to switch back and forth. Or you end up having to move a lot of stuff over to the new profile.
For windows 7 Microsoft also explains how to change your existing user profile here: http://social.technet.microsoft.com/wiki/contents/articles/19834.how-to-rename-a-windows-7-user-account-and-related-profile-folder.aspx
