run time error

Hi, it was a windows application,

1-      Error is coming when i need to run the program, (when double click on the .exe file)

2-      The error appears before the form was open

3-      i think that the error done in the calling of the class that contains the database connections , because i try to run an application without database connection (simple application just text box and button) and it's run well.

First of all many thanks Neha for your Interest.
I  developed  a program name " pricing" this program connected with access file to get and set data, I use this program in our office and there are 4 persons  with 4 machines uses this program, 2 PCs Win 7, and 2 PCs Win XP .
The important thing was to make the access file share to all PCs  to union the data, for that Iused our partition in a server of the company to copy the program over it, and run the program from the server, the program run well with 2 PCs with win 7 and make error when runs with 2 PCs win XP, Knowing the program run well in local machine over 4 PCs.

NOTE: I'm using in the program Visual Basic Power Pack 3.0

Then please elaborate more.
