There's a free program called "dependswalker" at
http://dependencywalker.com/ which may help you (there are 32 and 64 bit versions.) Basically, you run it like this:
Start dependswalker
Open tgd.exe (from the file|open menu n dependswalker)
profile it (from the Profile menu (Start Profiling) in dependswalker
View the resultant logs.
I would recommend stopping your virus checker (you may wish to try tg2 with your anti-virus program stopped anyway, just to eliminate it.) Also, it is not unusual to have errors like DEVMGR.DLL, IESHIMS.DLL, and WER.DLL called out. Those dll's are not usually the problem.
Any, you will get a long log file that may help pin-point the problem
