Could not load file or assembly CrystalDecisions.ReportAppServer.Controller


I am getting this error in Visual Studio 2010 on Windows 7 64 bit.

Could not load file or assembly 'CrystalDecisions.ReportAppServer.Controllers, Version=13.0.2000.0, Culture=neutral, PublicKeyToken=692....1304' or one of its dependencies. The system cannot find the file specified.

I installed CR redistributable on the workstation and verified that the file does in fact exist and is the correct version.

Please help.

    Which "CR redistributable" did you install?

    Is your app compiled as 32 bit or 64 bit?

      Hi Ludek

      Well I finally looked at the C:\Windows\Assembly folder on the server and it turns out the server has BOTH 32-bit and 64-bit Crystal Reports assemblies installed side-by-side. I didn't know that was possible. That must be why the first 3 assemblies got through the bulld and it caught on the 4th. So I installed the 32-bit version on my workstation alongside my 64-bit one and now the Crystal Reports error is gone! Guess I needed to have both.

      Thanks for all your help.
