What does the app do specifically? My guess would be that it's doing something that's incompatible with Windows XP if it worked in previous operating systems.

Have you tried tracing it to see at what point the app fails?

Agree with Glenn, and you should seriously consider moving development (Delphi) to XP, if you haven't already.
If you are already running under XP, then as Glen says step through the program to see where the problem is.

But we probably need more info, what Operating system are you using? Which version of Delphi? Have you re-compiled the code? etc

Thanks Glen and sggaunt
The guy who wrote application with Delphi 4 under windows 98( 10 year ago), the application works fine in windows 98, when I install and run under windows XP, It popup and disappear.I tried many XP machine they are the same problem.
It is about Runtime like Visual Basis? - I used VB6 it need Runtime, but don't know much about Delphi.

Many Thanks

Delphi doesn't need a runtime for basic operations like Visual Basic. In fact, I use Delphi 3 all the time under XP without problems.

Therefore, for what you are working with, it comes back to what we have been suggesting. Get a copy of Delphi (4 or whatever) installed on an XP machine, and step through the code to figure out what part is causing what you are seeing.

You could try rightclicking the program you're trying to run, then select Properties.
In the window that pops up:
click on the Compability tab, Check the "Run this program in Combability mode for:" and select Windows 98 in the dropdown list.

If that does not solve it you should recompile the program in XP, if the source is still available

Where can I buy (find)Delphi 4 or 5 compiler?
I know it is old software.

Your delphi Code should work in versions greater that Delphi 4. You can purchase in many places. In addition, limited versions may still be avilable for free. Google Turbo Delphi and see what is avilable na dwhat limitations on use apply for you. Some earlier Personal releases do not include Databaase capabilities so, the usefulness of these downloads will depend on what fetarures are in your code.
