Error: Cannot connect the computer to the server because either another software installation is in progress, or, the computer has a restart pending.

I have been seeing quite a number of systems coming up with this error message when attempting to install the Client Connector Software for SBS 2011 Essentials.

“Error: Cannot connect the computer to the server because either another software installation is in progress, or, the computer has a restart pending. Either complete the installation process, or, restart the computer and try to connect again.”

The first thing to do is obvious – Reboot the computer. But then again, there would not be anything to blog if it were that easy. Obviously, that has been attempted and the error remains. Apparently, this is often caused by programs not cleaning up their installation settings.

The fix is fairly simple, if you can remember where the registry setting is.

Open up Regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager. Rename the key named PendingFileRenameOperation to something else.

That should resolve the issue.

  1. I’m having the same issue as above. However, I do not have a Registry key by that name in my registry. I’ve read on other sites to change the system clocks to the same time and or Pacific time, didn’t work. Also read that some Logitech WebCam’s cause this problem and to uninstall it and install the connector software. Tried this with same result. Any other ideas? All are wired.

    PC Servers Specs:
    AMD Phenom x4 2.8 Ghz
    8GB RAM
    250GB Hardrive (OS: Windows Home Server 2011 64bit)
    2TB Hardrive (media, backups, data, etc)

    PC having problems:
    Windows 7 Home 64 Bit
    AMD Phenom x4 2.8 Ghz
    8GB RAM
    1TB Hardrive

  2. Thanks for the reminder. Have only added PCs to a SBS once so I couldn’t remember what the fix was for this. Very easy to do and it worked right away. I have also seen a “Fix It” program that does this same thing (that’s how I fixed it last time).

    Thanks Again!
