Could not load file or assembly 'CrystalDecisions.CrystalReports.Engine

[dave_smith2]

We have an ASP.NET/VB.NET application using .NET 2.0 and Crystal XI Release 2 installed on a web server. When we attempt to access a Crystal report, the following message is received:

Could not load file or assembly 'CrystalDecisions.CrystalReports.Engine Version=11.5.3700.0

The file does exist on the server and was installed properly. Accessing the same report using the COM SDK and craxdrt.dll works properly.

Any special steps that need to be taken to correct this? Does this module need to be registered in any specific way?

Hi,

It is mandatory to deploy correct version of runtime files.

You can also download runtimes from https://www.sdn.sap.com.

Goto BusinessObjects Tab and then click on downloads.

For downloading from this site [Click Here|https://websmp230.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/bobj_download/main.htm].

For VS 2005 and CR XIR 2 these are the latest Server Install files .[crxir2fp52_net_si|https://smpdl.sap-ag.de/~sapidp/012002523100004610722009E/crxir2fp52_net_si.zip].

Hi,

- How are you Deploying your Application ?(Using Merge Modules or Server Install).

- Which MSIs or MSMs your using for your application?

You can download runtimes from [here|https://www.sdn.sap.com/irj/scn/wiki?path=/display/bobj/crystalReportsforVisualStudio.NETRuntimeDistribution-Versions9.1to12.0].

Also,check the the runtimes installed at c:Windowsassembly folder.

Hi Nikhil,

Thanks for the response. We did not use any merge modules or MSM, it was a server install of CR XI. I checked the windows\assembly folder and found only one instance of CrystalDecisions.CrystalReports.Engine - v11.5.3300.

It looks like the version we need is not installed - v11.5.3700. I guess this is for VS2005.

Can we use the runtime files you suggested to install the correct version? Which one should we use? CrystalReports11_5_NET_2005.msi (.NET 2005)?

Thanks for your assistance.

Yes. CrystalReports11_5_NET_2005.msi is the installer you should have used to get the .NET 2.0 assembly files (11.5.3700).
