Hi folks, I'm new to the forum, and came here hoping someone had found a solution. I know what the problem is, at least for an unmodded game: MVP Baseball 2005 uses SafeDisc v2, which uses a file called SECDRV.SYS to validate the disc. This normally shipped with Windows, but Microsoft appears to have pulled it from Windows 10. Every game I have tested that uses this form of copy protection exhibits the following behavior: - If you try to run it, you get told to log in with Administrator Privileges and to try again. - If you then set "Run as Admin" compatibility mode, the message disappears, but the game doesn't start. - Keeping a window open for C:\WINDOWS\SYSWOW64\DRIVERS shows SECDRV.SYS appearing (apparently put there by the game) at the moment you try to start the game. - The Windows event log shows that SECDRV.SYS failed to load. The problem, it seems, is that the failed driver load is making these games fail their copy protection. On my Windows 64-bit 8.1 system, C:\WINDOWS\WINSXS has a folder called amd64_macrovision-protection-safedisc_31bf3856ad364e35_6.3.9600.16384_none_4e6b3758913c9240 with a SECDRV.SYS in it, presumably the one that ships with Windows. Windows 10 had such a folder in early builds (I found this by looking at error logs posted online), but it is missing from the release build.
