I encountered an issue today where multiple products installed on Windows 8 would not launch. Also, Internet Explorer launched and crashes within a few seconds. Trying to repair one specific product (CISCO AnyConnect) with its MSI resulted in the following error message…
The Event Log showed the following error message.
What appeared to work for me was running the following command from the administrator account…
SFC.EXE /scannow
One reboot later and Internet Explorer worked and other products that also failed to launch worked without need to repair them.
