Has anyone ever seen this error when trying to run software updates?  I could use a fresh perspective and believe I’m close, but can’t quite seem to put 2 and 2 together.

“This installation failed to start because another update installation is in progress.”

In srvpack.log on the client I see this error:  Service Pack 3 Setup encountered an error:  The  update.ver file is not correct.

Upon reboot, the system says it’s at SP3, but the remaining updates will not install because it still thinks another update is in progress.  Nothing exists in HKLM\Software\Microsoft\Windows\CurrentVersion\Installer\InProgress

Any ideas?  I’ve been all over the Internet today looking for an answer to this one. 

Checked this KB http://support.microsoft.com/kb/949384/ and doesn’t apply.

One KB article (822798) lead me to \system32\Catroot2\edb.log.  I am unable to open this log file because it’s in use by another process.  There is also an edb.tmp file in there as well, but cannot open it for the same reason.

UpdatesDeployment.log shows
