hello, i work on some dos programs and on some dos programs. when i realized that i was in the ancient world since i was using windows 98. i decided to upgrade to xp. but when i upgraded, the dos programs did not work. I contacted some computer engineers and they said that xp did not support dos programs. but i can't afford to leave the programs, so i again went back to the acient world i.e. win98. Isn't there any program or any other way that can help me run my dos programs on xp. since i was lacking many things for not using xp, i at last had an idea and had both the two os installed on two different partitions. i is working temporarily but............ hello everyone, i tried all the replies received by you but unfortunately none of them worked. I am still unable to run Tally 4.5 on windows XP. I know that Tally 7.2 is available, i have it, but Tally 4.5 is Tally 4.5. I want to continue using it.
