Service Pack 1 Installation fails due to a previous installation

I'm attempting to install the Exchange 2007 Service Pack 1 update and I receive the following message in the Prerequisite check:
**
Error:
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.

Any suggestions?

Funny how things never change huh?

Look at the HKLM\SYSTEM\CurrentControlSet\Control\SessionManager\PendingFileRenameOperations and see if there is a value there

if, after you rebooted the machined, there are still some keys there, delete them and try installing again

worked for me :)

http://support.microsoft.com/kb/q312444/ link does not work, can you post the correct link.

thanks.

Also found that the MS link posted here doesn't work. Had this same error attempting to install MS Exch2K7 Mngnt Tools on Win Server 2008 machine. Found another article which recommended clearing the contents of the following registry key:

HKLM\system\current control set\control\session manager\PendingFileRenameOperations

This worked perfectly for me.

The link is no longer valid, so the problem still persists for me.

Perhaps we can get in the habit of posting the contents of the link and not just the link? That way the accepted solution here would remain accepted. As it stand now, this post is entirely useless and yet another deadend 'accepted solution', making Experts-Exchange less useful as a solution tool.

I'm having this issue on Win7 64-bit with Exch ENT 64 bit. Any resolutions posted are much appreciated, I've wasted 3 hours of productivity so far on this.

Thanks in advance
