VB.Net and Crystal Reports

[http://www.visual-basic-data-mining.net/forum]

Hi,

I wrote a program in VB.Net 2003. The program includes some reports made
with Crystal Reports for Visual Studio.Net 2003.
On my computer (with Win XP Pro) the program runs as it should do.

When I install the program on another computer with Win XP, everything is
still OK.

But when I install the program on a computer with Win 98 (and with
NetFrameWork) the program is still running, except the viewing of some
reports (always the same).
When try to view one of these specific reports, I get the following
error-message: "Crystal Report Windows Forms Viewer: Object reference not
set to an instance of an object."

Who can help me?

Thanks,

John (from Belgium, Europe)

when you build your app for release, did you include a merge module for
crystal report components??

Yes, I included merge modules (Crystal_Database_Access2003.msm,
Crystal_Database_Access2003_enu.msm and Crystal_regwiz2003.msm), but I don´t
think that´s the problem.

The real problem is that the program runs 100 % on another computer with Win
XP, and doesn´t run as it should (everything is going fine except viewing
the reports) on a PC with Win 98.
