Pathloss 5 - Known issues
Some packages of MS Office 2007 include a program called Groove which runs in the background and conflicts with Pathloss. If it is installed and running on your system it will prevent Pathloss from starting. No window will appear and no process will be started.
There is currently no work around for this problem and Groove must be uninstalled. You can uninstall it by using the add / remove programs tool from the Control Panel. Select Microsoft Office 2007 and click the Change button. Select Add or Remove Features and click continue. Click Microsoft Office Groove and change the selection to 'Not Available'. Click continue to make the modification.
It is not necessary to remove Office 2007, only the Groove component.
