Service Pack 1 Installation fails due to a previous installation
Posted on 2007-11-29
I'm attempting to install the Exchange 2007 Service Pack 1 update and I receive the following message in the Prerequisite check:
A reboot from a previous installation is pending. Please restart the system and rerun setup.
The server has been rebooted multiple times between SP1 attempts, to no avail.
I originally attempted to install this prior to a large list of windows updates receiving this error, and then tried again after all the latests Windows Updates (for Windows Server 2003 64 bit), with no change.
I've also tried the "msiexec /regserver" command with no luck.
