If I attempt to launch the 13.x PlanAhead tool, I see a dos box open and it appears that the PlanAhead tool is running. However, after the "start_gui" command is issued, nothing further happens.
If the PlanAhead tool is launched from a Command shell, information similar to the following is written to the screen, but then the prompt returns and the PlanAhead tool does not open.

The 32-bit version of the PlanAhead tool (run "planAhead -m32") often works even though the 64-bit version will not launch.
The following options have been used successfully to get the PlanAhead tool to launch:
