I tried shutter actuations the other day and I couldn't figure it out. It just tried to load software that I didn't not want.
I'm sorry for that. I tried it on Windows 7 x64 and even on Windows XP x32. Both worked.
Don't worry about it. I shelled out the 1.79 and the shutter count was 2704 which is crazy low.
Upgrade path.->means the former was sold for the latter.
