pdf file believe to open in the background but could not be found.
This is a strange problem. When I first launch the Acrobat Reader apps successfully through desktop shortcut icon, opening all pdf file is ok. But once I closed the apps. I can't open any pdf file at all, can't re-launch the app from desktop icon too. It seem like it's running in the background somewhere but window task manager doesn't show that Acrobat Reader is running anywhere. Have to re-start the PC in order to launch it successfully again. What could be wrong? Can a tech remotely login to help?
