Apparently mfc80.dll is part of Microsoft Visual Studio 2005. You could try uninstalling that if you don't use it, or temporarily uninstall just to see if it is the problem. I don't see why it would be caused by the webcam if mfc80.dll is installed by Visual Studio and isn't a core part of windows or directx or anything. Did you have Visual Studio running when you ran freetrack?

If you want to be sure try uninstalling the webcam drivers, then go to control panel/device manager, find your webcam, right click and "uninstall". Try launching Freetrack and see if it works. If its the same thing I think we can be confident the webcam isn't the problem.

For me, freetrack 2.2 won't even start with my webcam unplugged and uninstalled so in my case it can't be the cause.

Thank you MRRocketShooz for the insight into visual studio but i believe i am not running visual studio so i guess some other thing is using those libraries.
I have gone back to the old stable version and now all works fine but still have to build a decent led setup to get it working properly...

Hope i don't lose to much features using the old version but will try again with new version once i get a external webcam for my main pc...


Thank you

No worries, good luck with 2.1! I'm still using it too for the same reason =)
