Considering that these are old games, and many of us have new versions of operating systems, it can be difficult, if not impossible, to run these DOS games. In Windows 10, Windows 8 and Windows XP, some games will not run at all. Windows 98 runs almost all games and older operating systems should have no problem running all games.
There is a solution for people who can't run the games. With the help of a DOS emulator, most games can be enjoyed the way they were meant to be.
If you are still having trouble running games, check out the Emulator-Zone Forum and hopefully you'll be able to solve your problems.
