Re: Sims Medieval won't launch on Windows 10

I can confirm this works.

There are 2 ways to enable SecDrv ......described here:

The 1st takes you via the cmd function - this did not work for me - it blocked the command but the 2nd method did. 

Using the Registry you add secdrv and assign a value. Sounds complicated but the detailed descriptions AND screenshots makes it easy. Honestly.

I did completely uninstall the game ( I had both disc and download) before making the system changes and then re-installed after; I don't know if that made any difference but thought it wise to do so.
