Canon MPNavigator EX 5.0 not working - will not open


Hello and thank you in advance


Issue: When clicking on the MPNavigator EX icon (or start menu link or the .exe file directly) the program starts (i.e. I see it running in Task Manager and if i try to uninstall, WIndow's tells I can't b/c it is runnnig) However, nothing opens up or shows on my screen.  

I have searched for hours.and unable to find a solution. I have tried deleting and re installing all drivers and software seveal times. And checked the user permissions for the .exe file.  

Any ideas on how to fix?


Canon MG5320 printer/scanner

OS: Windows 7 SP1 x64  (Home premium)
