Never used Crystal, so bear with me.

I’m using Crystal Reports 2008 (Version 12.0.0.683) Product Type : Full

From my .net project (asp.net mvc 4 / c#) on my local machine I can generate reports just fine. I create the reports in the background and convert to pdf. Not using the viewer at all.
However uploading to the server give me errors like:
“Could not load file or assembly 'CrystalDecisions.ReportAppServer.CommLayer, Version=12.0.1100.0, Culture=neutral, PublicKeyToken=692fbea5521e1304' or one of its dependencies. The system cannot find the file specified.

or
“An error has occurred while attempting to load the Crystal Reports runtime. Either the Crystal Reports registry key permissions are insufficient, or the Crystal Reports runtime is not installed correctly” when I try to run the report.

I downloaded and installed various redistributable s but the problem is I do not know what is the right redistributable and if there are other steps involved.

The server is Win Server 2008 Server 64 bit and I’m using IIS 7.
