Logon Pad for 7.20 Quits Immediately

Hello,

I just installed SAP GUI 7.20 on a machine and now any time I try to launch the Logon Pad or the SAP GUI Configuration, you see the SAP splash screen for a split-second and then it disappears.

SAP will not run, and if you look in Task Manager, the program is not running.

Any ideas?

The machine it is on is Windows 7.

I need to urgently fix this issue today if possible.

Thanks!
