While trying to save an image, Paint.NET throws an UnauthorizedAccessException and gives the message "Access is denied. Use File->Save As to save under a different location or name". This happens regardless of the path, quality and extension After the exception the application continues to run perfectly fine, but simply doesn't save it. The Exception was thrown with a few parts in Dutch, I translated them for the sake on convinience and I apologize if it's not 100% accurate. System.UnauthorizedAccessException: Access to registerykey HKEY_CURRENT_USER\SOFTWARE\paint.net is denied.
