I launched TMG v. 8.0 this evening, and received a screen informing me to upgrade to version 8.01. I followed the instructions to perform the upgrade.
Near the end of the upgrading process, I received a message saying that C:windowsSysWOW64bbLitViewV.ocx failed to register and to contact support personnel.
I clicked on cancel and the screen went away, and a TMG screen appeared telling me that the upgrade was finished.
I tried to launch the program and got a message that c:windowssystem32bblistviewv.ocx could not be found.
I went to the Whollygenes site and clicked the link to download the TMG software, and reinstalled it. The problem seems to be resolved as the program now opens.
