How to remove partially installed Office 2010 for installing it again?

In certain situations the installation process of Office 2010 freezes before completion, you cannot rollback it or uninstall it as there is no entry for this installation in the Add/Remove list. Moreover it’s also impossible to install any other version of Office (such as Office 2007).

You can try to manually uninstall Office 2010 by the steps below as suggested by Microsoft:

1. Download and install the Windows Installer Cleanup Utility.

2. After you install the Windows Installer CleanUp Utility, click Start -> All Programs -> Windows Install Clean Up.

3. Highlight Microsoft Office 2010 entry in the list and then click Remove. Quit the Utility.

Note: If you have got any other old or redundant office entries such as Office 2007 or other Office stand alone products such as Visio in the list, please remove them together.

4. Close all applications.

5. Click Start, in the Search box, type “regedit” (without the quotation marks) and press Enter.

6. Expand the registry tree on the left pane and locate the following two registry subkeys:

HKEY_CURRENT_USER – Software – Microsoft – Office
HKEY_LOCAL_MACHINE – Software – Microsoft – Office

7. Right-click on this registry subkey and click Delete to delete those keys.
8. Open Windows Explorer, and then browse to the “C:Program Files” folder

If it exists, rename the “Microsoft Office” to “Microsoft Office OLD”
If it exists, rename “OfficeUpdate” to “OfficeUpdateOLD”
If it exists, rename “OfficeUpdate14″ to “OfficeUpdate14OLD”

9. Click Start, in the Search box, type “%Temp%” (without the quotation marks) and press Enter.

10. Empty the Temp folder.

Note: If some files can’t be deleted, please skip them, which don’t influence the result of the troubleshooting.

11. Empty the Recycle Bin.

12. Restart your computer. Try to install Office 2010 again.
