Hello All,

I am frustrating unable to run most of dos base program as well as some other program like "Maria", "Air Assult II" etc.. How to solve this problem? Your suggestions are HIGHLY appreciated. Thank you

IndraIt is more useful to know the operating system you are running to help you. There is a way of running dos BASED programs in all of them.

This one is for XP

Windows XP
Many older computer programs MAY not run correctly if you just click on the program's EXECUTABLE file in Windows XP; this is particularly true of older game programs. There can be many reasons why. Perhaps the program uses DOS calls that XP does not know about. Perhaps there are GRAPHIC hardware considerations. Perhaps...who knows.

Indeed, some older DOS-based programs, in order to speed up the display, wrote directly to the computer's hardware. These, Windows XP will not allow to run at all. In order to run these you will have to find a computer with an older operating system or a good emulator or virtual computer (see below).

For those in between, there is some hope in using Windows XP's Compatibility Mode.

Open Windows Explorer and navigate to where the program is located. Then...

•Right click on the program file (the .EXE or .COM file).
•Select Properties from the menu that pops up.
•Select the Compatibility Tab in the dialog.
•Change the options so the program opens in Windows 95 or 98 compatibility mode. Note the other options in the dialog as you may have to experiment a bit and change some of them as well.I have done as you mentioned in this thread but nothing would happened. Could you please suggest in other way....What is your operating system? XP or Vista or Windows 7 ?At first, I had Windows XP but now I have installed Windows 7. In both operating system have same problem....You could try using the dos box emulator from  http://www.dosbox.com/Thank you very much....I will test with it....It is said that AMD processor has such problems.. is it?
