I need to update Windows Installer to 4.5 on Windows XP (Hotfix KB942288) but it has to be done without a reboot. Some software we're trying to install requires WI 4.5 but it's on a computer that cannot be restarted. It runs on a multi-site HA VMWare ESX cluster and we need to keep it as close to 100% uptime as possible (Our SLA is 6 nines), the services it's running don't support Windows Server or their own HA/clustering so we must keep a single instance up all the time. We can't even run security updates.
Is there any way to get the WI 4.5 update fully installed without a full reboot?
Post;
I know nothing that needs 6 nines uptime should be run on a single instance, but the software doesn't support any form of clustering, failover, replication, HA etc. I've never had anything to do with this server before (I'm actually a UNIX sysadmin but I've been pulled onto this for some reason unknown to me).

Argh, just tested in a VM, can't see an easy away around it requiring a restart - sorry :( – William Hilsum – 2011-08-10T07:58:40.920
Pulling a UNIX IT tech over to Windows? sounds like a fall guy to me. The Unix guy screwed it up, your fired! – Moab – 2011-08-10T16:37:24.463
In short, no, some updates modify parts of the registry that require a restart, no way around this, its WINDOWS not Unix. – Moab – 2011-08-10T16:39:03.043
