On another thread that has been marked as solved, the suggestion was given, "Create a folder on your desktop called "Office.en-us". Find the same folder on the CD and copy "OfficeMUISet" to the folder on your desktop.
Re-insert the CD so that the setup starts again.
When it tells you it cannot find the file and wants you to select a folder, click on DESKTOP.
It takes a minute to get started but it will install just fine. "
I tried that and it says, "Cannot copy OfficeMUISet: Access is denied. Make sure the disk is not full or write-protected and that the file is not currently in use."
Any other solutions?
