I have a c# app which run fines and give the expected results in windows XP but when i run the App in windows 2000 it gives me strange results although I'am using the same inputs that i Used in XP.

and already i had installed the .NET Framework 2.0, MDAC 2.8 and Windows installer 3.o .

In Details:

I have a c# Windows Forms App which open's up 2 excel files and read them to a dataset and save the data set in an arrayList for the first file and another arraylist for the second file and it compares those 2 array list and give result in rows that match

so when i run the App in winXP i get 342 Matchs but in Win2000 only 10 Matchs

I dont know what there is in the XP that the Win2000 Needs to run .Net App normally just like the XP?

Is there any Fix's for this so i can download ?

Please Help and thanks for your time
