Only CR 10.5 and CR 2008 (12.x) are supported with .NET 2008. See [this|https://wiki.sdn.sap.com/wiki/display/BOBJ/WhichCrystalReportsassemblyversionsaresupportedinwhichversionsofVisualStudio+.NET] wiki for more details.

What CR assemblies are referenced in your project?

What is the version of the assembly crystaldecisions.crystalreports.engine.dll used in the project?

Let's got with v12 then. Make sure you do not have any other versions referenced in your project.

Download SP3 from here:

https://smpdl.sap-ag.de/~sapidp/012002523100007123572010E/cr2008_sp3.exe

See if that helps.

Hello Ludek Uher,

it's seems to me, that I have the same issue as described here, but I can not open any of the links here in.

I get a NullPointerException on a Windows Server 2008 R2 (64-bit) machine using crystal report runtime 2008 (SP 4). I try to export to a pdf file and in my development environment everything runs fine.

I checked already if the program which calls the crystal report runtime runs in 32-bit mode. And it does so.

My crpe32.dll has the file version 12.4.0.966

I hope there is a solution for my problem too.

with best regards

Mirko
