   Note When you view Add or Remove Programs, look for Office programs that you thought you had removed that may still be present on your computer. If you find any programs that fit this criterion, remove them.
2. Open an Office product, click Help, and then click Detect and Repair.

 Repeat this process for all your Office programs. If the Detect and Repair process fails, your Office installation source/cache may be corrupted. If this is the case, run the FixIt from the following article. If the Detect and Repair process and the Uninstall process still fails, you must manually remove the Office installations - please contact Microsoft Support as noted above:
