How to fix cannot connect the computer to the server because either another software installation is in progress…

 

On some Windows client machines, you may receive the following error message when you attempt to install the connector software for your Windows Home Server:

“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.”

Even after multiple restarts and software update checks the error may still persist. The fix requires an edit of the Windows registry as follows:

1. Open regedit
2. Navigate to the following registry keys: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Session Manager
3. Rename  ”PendingFileRenameOperations” to “PendingFileRenameOperations2″.
4. Exit regedit.

Any application can set a pending reboot flag in the operating system through a registry key. Sometimes a reboot does not clear the flag. This is what setup is detecting when it fails to install the connector for your Windows Home Server.
