Problems caused by Power lost during installation of Open Office

[hkcat0]

I clumsily kick off the plug during Open Office installation. After
the machine reboot, I cannot reinstall OO again. Actually I cannot
install anything that need Windows installer. An error message say
that my windows is in safe mode or windows installer is not properly
installed.
I search through google.
I have checked the registry, it is pointing to msiexec.exe correctly,
I have unreg and reg the services in safe mode and normal mode,
I have tried manually start the windows installer service but it stop
immediately,
I have renamed msiexec.exe, msi.dll and msihnd.dll to other name and
install windows installer with the latest download. the installation
complete successfully but no new msiexec.exe and dlls are created.
I have run regclean but there are still some Open Office entries in
registry that whenever I click on it an error message report that there
is an error opening the entry and refuse to delete it.
I don't have any sytem recovery restore point.

My machine has a Raid 0 array of harddsiks with 500G of DATA. I don't
want to risk lossing all the data by reinstall Windows. Backup the
data to 100 DVD-R is not quit possible. Is there anything else I can
try beside reinstall Windows?

Try CHKDSK <drive letter>: /R /X in command line.

I have had some luck with the Windows Installer Clean up utility in
cases like this:

It is worth a shot, you just install the program, then run it and
remove the entries pertaining to the problem piece of software. It
works with any program installed by the Windows installer not just MS
Office.

Good luck

Thank you for your advice Jlanners, I downloaded it and try to install
it, but I have bad luck. The Clean up utility itself need Windows
Installer to install. This is like the Bios error "No keyboard is
detected, Press F1 key to continue."
