Setup detects reboot required for install/uninstall

The AT&T Global Network Client installation package can sometimes display an error indicating:

Setup has detected that a reboot is required to finish an installation or uninstallation.  Please reboot before running this setup again.

This message indicates that the registry key:

HKLM\System\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations

is present and is not blank. This means the operating system thinks it has a file to rename the next time it reboots the workstation. This key is managed by the operating system itself and is not tied to the AT&T installation package. However, Microsoft installation best practices indicate that if there are pending file rename operations we should not proceed with the installation as a previous installation/un-installation may have altered a file which required a reboot, but the user has opted to continue working and reboot later. Because allowing another installation to proceed under this circumstance could cause unexpected results, installation packages that adhere to the recommendations will display a dialog such as ours does asking the user to reboot their workstation to allow the operating system to clean up that pending file rename operation.

If rebooting your workstation is not clearing out the registry key, you can manually delete that registry key and that will allow the installation to proceed.  If you are unable to delete the key you can also try renaming it.

Always create a System Restore Point prior to making any manual edits to the registry and use great care when deleting anything from the registry.
