Error Msg: Could not load Crystal Engine 10.2.3600.0

Hi,

I am creating a Visual Studio 2008 project using Crystal for my reports. I will be creating the reports through a Windows service, which references "CrystalDecisions.CrystalReports.Engine, Version=10.5.3700.0". The file for 10.2.3600.0 is nowhere on my computer. This is not a deployment issue, since the error is thrown when I try to launch the Windows service locally on the development computer. Why would this file be looked for? I look in the GAC and only the 10.5 version is there. Any suggestions or thoughts?

Thanks

Paul
