Helo, i met with a trouble recently with dos based application, and i need some help here.

I have a dos based application, previously running well in windows 98, but because of bought a new pc system, i wish to use the application in my new pc, running XP. But unluckily, it shows "Not Authorized program!" everytime i try to run the .pif file, or even directly running the .exe file.

can someone help me with this? thanks.
your help will be very much appreciated!~ :)

my email, wtecom@yahoo.com

!!URGENT!!

**if anyone need the program, i can email it to you to give it a try**

If its a true DOS program (not a Win95 port), you can use DosBox (not the command promt within windows, a seperate program) to run it. If that fails, you will need to install an earlier version of windows in order to run it.

In Windows Explorer, navigate to the executable program, right-click on it, select Properties and then select the Compatability tab, select the "Run this program in compatabiluty mode" check box and select Windows 98 (or whatever) from the list and click OK.

If you still have your 98 disks, you can download Virtual PC from Microsoft (free) and make a virtual 98 machine in it. Should be a solution for you.
