Crystal Report Error: Could not load file or assembly CrystalDecisions.ReportAppServer.Controllers

Hi varun.p,

Which CR redistributable did you install?

Is your app compiled as 32 bit or 64 bit?

Please install correct version of CR for VS 32 bit or 64bit based on your operating system.

Or refer below links.

i solved this error. i install both 32bit and 64bit version in my machine then run application and easily open crystal report and never got this error again.

Thanks.
