Q: in start menu ,in canon utilities, the photoStich exists but does not run(it starts to search for the source of application) and also the uninstall icon exists too, and that one does not work either! Trying to install a fresh copy ,it says you have already installed PhotoStich 3.1 and don't need to install again!!
A: I think in this problem I recommend using Registry Mechanic becuase this program helps to fixing computer problems like this one that your having problem with plus it helps to tune up your computer to run more faster and smoother.
