Ok, I assume it's not possible... Isn't it?? The thing is, I install Office from an administrative source with ALL updates already integrated, during RunOnceEx phase - and it works great, BUT Microsoft Update insists on installing about 10 critical updates for Office, which were already installed at the previous stage, as I've already mentioned. I read about updates for office offered by MU even if Office isn't installed, just because there are some apps which install Microsoft Office 2003 Web Components along with them... Maybe telling Office not to install this feature in first place would help; Haven't tried it yet, and I prefer not to, unless there's no other alternative... I've already tried using a pre-made DataStore.edb (which is about 40 Megs because of that), with not much of a success (less updates are offered, but there are still some)... Any other thoughts or ideas??? It's driving me nutts! Thanks in advance, Ran.
