Usually with stronghold this means that it may have detected a virtual drive creator, examples would be Daemon tools, or Alcohol 120%, Power ISO. These are usually used when people steal the game images and mount them on the virtual drive to play them without paying, this is not always the case, but the companies take the first step and try to get the game to deny anyone with those installed if it can find them. You should really look on the stronghold 2 forums for the answer, I would be surprised if they couldn't tell you.

This problem happens when I try to launch SHC+E or just SHCE. Error: Problem signature: Problem Event Name: APPCRASH Application Name: Stronghold Crusader.exe Application Version: 1.0.0.1 Application Timestamp: 4a66f6ce Fault Module Name: Stronghold Crusader.exe Fault Module Version: 1.0.0.1 Fault Module Timestamp: 4a66f6ce Exception Code: c0000005. Jul 23, 2018  It has been working perfectly up until now, when first the cursor disappeared and now the application will not open. I have deleted the app and re-downloaded and reinstalled, but this has not fixed anything. When I try to open the app I get this message: “Stronghold Crusader HD.app” is.

Anyways if any of those are installed you may have to uninstall them, or hide the drives to play it. If not, check their forums.

I found this on a site named stronghold heaven. It basically reiterates what I said, just includes things I missed.Q: When trying to start the game I get this message: 'A required security module can not be activated' or 'Emulator detected' what do I do?A: You get that message because the SecuROM copy protection for the game detects Virtual Drive software on your computer.
