Windows Server2008, C# and CRRedist

We experience some strange behaviour:

on WTS with OS 2008 or 2008 R2 we get an error from CR runtime engine.

'either the authenticity of the crystal reports registry key is not valid or the runtime was not installed correctly.'

But: this only occurs with a module which is compiled with C# code only.

The same module, when I call it from a VB-compiled parent prints fine after I've had initialised the CR viewer once within the VB module.

On WTS with Server2003 everything works fine.

As well as Windows7 workstations ...

We use VisualStudio2005 (8.0.50727.762), CR 2008 ( and there is CRRuntime_12_2_mlb.msi installed on the WTS.

Has anybody any idea what can be done ?

    I doubt you'll get any answers from the database forum so I moved you SDK question to the SDK forum

    No idea anyhow ???

    I've found a similar thread [here|Crystal Reports Runtime: Null Reference Exception;

    But there has been at last no answer bout the version of crpe32.dll version by Ahmed.

    On our server we have

    Is there still no runtime for 64bit OS available?

    nevertheless: the ridiculous thing is, that compilation is running but c# is not

    should i mention that the dll is programmed in vb ???

    • Wow. It was another one of those "shoot and hope" :). Thank you very much for letting me know. I think as we enter the brave new world of 64 / 32 bit runtimes, we'll see interesting issues. I'm planning to write a blog on what to consider - as far as Crystal Reports is concerned. The blog is in the back of the mid stage right now, but by the time CRVS2010 ships (perhaps as soon as end of this month), I'll have it out there.
