Mine does similar (XP SP2), though I don't use Kaspersky.

Make sure your Windows Installer service is started.

For some unknown reason, although my Installer service is set to auto, it 
needs to be started manually whenever I want to install new software.

You didn't mention that you've check Services to ensure that Windows 
Installer Service is actually started. I think it also needs a dependant 
Service to run before it will start.

Once running, my MSI stays enabled until the next reboot. Then it needs to 
be restarted again.

If, perchance, you've uninstalled MSI.exe and have now been left hung out 
to dry, won't System Restore restore the original MSI.exe?
