I'm beginning to test ZfDAgent 7.0 SP1 IR4 HP4. I have an HP3 machine
(WinXPsp3). During the install of HP4, it rolls back. Unfortunately, it's
not truly rolled back. The agent is left completely broken. If I reinstall
HP3, reboot, then it's fine, but re-trying the upgrade to HP4 causes the
same situation again.

I have an MSI log with full logging (voicewarmup) enabled, but I'm not sure
how to decode where exactly the problem is.


Thank you.
