Hello all Okay ..a possible solution to MVP2005 running on WIN 7-WIN10. During the Win.Sept 2015 updates Microsoft has disabled the "SECDRV.SYS most older games used for pirate protection. You can read it here: http://www.kotaku.com.au/2015/09/new-update-for-windows-7-and-8-kills-safedisc-copy-protection/ I tried the steps in the above site and it didn't work (Win 8.1) so, all I did was uninstall the WIN Update : (KB3086255) Sept 10 2015 file, and my game started as normal. Hope it works for you.
