Installer Cleanup Utility problems

[Griff]

Running XP Pro SP3 and Office SR-1 Premium. After installing then
uninstalling a buggy program, Office advised "This program must be installed
to run...etc." Initially I tried Add/Remove Programs-Change-Repair and
Re-install, but no change. The date of last use is reflected as 08/02/2008!

Then Installer warned "The patch package could not be opened...". After
reading kb and forum info, downloaded and installed Installer Cleanup Utility
msicuu2.exe. During installation the following errors occur:

Internal Error 2908. {121634B3-2F4A-11D3-ADA3-00C04F52DD52}
Internal Error 2908. {121634B5-2F4A-11D3-ADA3-00C04F52DD52}
Internal Error 2908. {BF1C5C32-2FC9-11D3-ADA3-00C04F52DD52}
Internal Error 2908. {121634B6-2F4A-11D3-ADA3-00C04F52DD52}
=== Logging stopped: 19/04/2010 14:50:47 ===

The installer ended with a "successful installation" and the utility was
placed in the Program items, but runs with the same errors in the log above.

Have also tried:
System Restore to a date before the problem - not achievable.
Using CCleaner to clear registry orphans.
Removing other user profiles, leaving only myself as comp admin.
Updating Installer to v4.5
De-registering and re-registering Installer msiexec.
Using services.msc to check Installer set to manual.
Running sfc /scannow with orig XP SP1a CD.

Nothing changes - so cannot use/uninstall/install Office.
Hope someone can help - please!
Thanks and regards
