Error #1321 MOS 2003 Setup

MOS 2003 Pro install setup error on Win XP Pro SP1. I was having trouble
getting the BCM add-in to associate with OL 2003. I was asked to uninstall
BCM and MOS 2003 Pro and then to reinstall MOS 2003. MOS 2003 was working
fine. With support help from MSFT Office specialist (not Convergys) we
meticulously deleted the appropriate reg keys and files. We were going to
use the Windows Installer Cleanup Utility, but it didn't list MOS 2003 so we
did it manually.

I am getting the following setup errors and setup stops when trying to
install wisptis.exe. Wisptis.exe is unfortunately installed with MOS and it
works with tablet PC. If you don't have a tablet, it stubbornly starts and
helps itself to CPU. Just ending it as a process or trying to use msconfig
won't stop it. A CPU gobbler that far and away most of the population
dosn't need as a gift from the MOS developers and product team with every
Office installation is ridiculous, but someone at Redmond made that call.
These two links context how to get rid of it and I used one of these tools.
They work and wisptis.exe disappears from your procdesses. Now I think this
is causing me problems on the reinstall.

I took steps here to uninstall wisptis.exe:

I'm getting this Error: Error 1321: Setup cannot modify the file
C:\Config.MSI 3a5322.rbf. Verify that the file exists (it doesn't) in your
system and that you have sufficient permission to update it. Should I
search for this to download it? Could it possibly have been eliminated iin
getting rid of the wisptis.exe annoyance?

This KB deals with the error in Office XP and recommends checking a registry
value here. My value is correct and conforms with this solution:

HKEY_Local_Machine/Software/Microsoft/Windows NT/CurrentVersion/Winlogon
1.. In the right pane, right-click AllocateCDRoms, and then click Modify.
2.. In the Value data box, type 0 (zero), and then click OK.

3.. Would appreciate if anyone has suggestions as to how to overcome this
setup error.

TIA,
