I run PokerTH Portable from my HDD while I have a USB drive plugged in. I run the updater from the stick and update my apps, including PokerTH. Rightly, it tells me to close PokerTH so it can update the copy on my drive. But when I hit "Abort", the comments-window still says "Install complete" which it shouldnt imho.
I am on Win 7.
