I found a video on youtube here that illustrates the problem i'm having perfectly.
Anything that uses InstallSheild to install does exactly that, start up, prepare the installation and then go into a minimized state and never emerge again.
I'm running windows 8.1, and it's a fairly fresh install, so there wasnt alot of time for me to much something up.
I've allready look around alot for a fix, so I'm going to list what i've tried:
AntiVirus (Malware bytes)
Checking if the service is running in services.msc
Microsoft Fixit (Which apparently was abandoned)
Sighing alot and rolling my eyes.
I dont know how many things use InstallShield, but I know it's enough that this is a serious issue for me.
All I wanted was to play blu rays.
