Here is an article with steps similar to that for Win 10 but has more of which relate directly for Win 7.
See how you get on trying them - unless you already have - https://support.microsoft.com/en-gb/help/2688326/can-t-open-exe-files-in-windows-7-or-windows-vista
So I assume you have performed a sfc /scannow ?
As you have Win 7 Ultimate, do you have an install disk for that ?
See if the program and the others will open in Safe Mode with Networking.
All 3rd party programs are isolated in that mode should it be something installed on your computer.
That error code is for Access Denied and could point to your antivirus program doing the blocking.
