When I was trying to renew my SAS 9.4 on Win8.1 pro, this occurred.
Has anyone encountered the same problem and successfully sorted it out?
You need administrator access to your computer to perform this task. Also check you have write access to the above folders by copying a test file into them.
You also need to close any instance of SAS that is running on your computer (including in background). Sometimes it is easier to reboot than to wade through the task manager.
