Restart manager causing unnecessary restart messages

Bob K

When I run my installation on Vista or Server 2008, I have noticed that on
occasion I get a warning that "critical" services are holding files open,
and a reboot will be necessary. This is untrue! In fact, if I say "OK" and
let it go, it completes without requesting a reboot.

I'd like to address this. Is there any way to determine what file is being
held open? Here is an excerpt from the install log:

MSI (s) (64:2C) [12:00:41:737]: RESTART MANAGER: Did detect that a critical
application holds file[s] in use, so a reboot will be necessary.
MSI (s) (64:2C) [12:00:41:737]: Note: 1: 1610
The setup must update files or services that cannot be updated while the
system is running. If you choose to continue, a reboot will be required to
complete the setup.

Thanks for any help,
