Do you have Crystal Reports 9 installed on the 2K?

 

[sahernandez]

no, but I don´t need to install CR9 over each machine or should I install it.

Over Win Xp works fine.

Did you include the merge module while deploying CR9. CR9 requires this merge module while deploying it with .NET app.

Here is the link to merge module if you don't have it already.

Yes I already did it.

I have a Bundled Version of CR9 and VS .NET 2002.
And I added this merge module:

Database_Access.msm
Database_Access_enu.msm
Managed.msm
RegWiz.msm
VC_CRT.msm
VC_STL.msm

But the point is, for XP run fine only in Win2k I found some problems

Cheers

If the report uses a DataSet as a report source, you may need to install a suitable version of MDAC on the W2K machine.
