Workaround
There is no known workaround at this time.
Resolution
Resolution 1
Verify you have write access to the folder where the product file is located.
- Click the Start button.
- Click My Computer.
- Navigate to the folder where the product file is located.
- From the File menu, click New, Text Document.
- Change the name of the file to "test file" and press Enter.
If you receive an error message at either step 4 or 5 then you probably don't have write access to
this folder. That is typically caused by either a network share that is setup for read-only access or
the user security on the server is configured for read-only access. Contact your systems
administartor to change the access to read/write.
