If you are following the script on reddit, it might be worth noting that this part: I'll get in trouble if I post option 4 - it would also stop the NAM from installing - but there is another way if you know about these things.I prefer to use DRM-Free software personally and highly recommend GoG (Good Old Games). Buy a digital copy of the game, during sales this can be under $5/£5/5€ in price.Get a digital copy of the game, Origin will replace it free if you ask them nicely it seems.Use a workaround to re-enable the secdrv.sys driver - See MS support article above.In short this means if you've a CD version of SC4 (and indeed many other CD-Based games using similar technology/DRM) you will find it will no longer work after installing the update. Information on this update from MS themselves can be found here. Unless you want or know how to manually digitally sign a driver for your OS (not recommended). It should also be noted that this update/change is a mandatory part of Windows 10, there is no real workaround for Win10 users. So it appears that Microsoft have decided that secdrv.sys, the driver for passing the Safedisc CD validation check, is no longer secure and a recent MS update KB3086255 will disable it on Windows Vista, Windows 7 and Windows 8/8.1 systems.
