What runtimes are needed to deploy an ASP.Net website with Crystal Reports to IIS?

Hello everyone,

I have a VS2015 ASP.Net website that has a Crystal Report that runs fine locally.  My local PC has the following installed:

• SAP Crystal Reports runtime engine for .NET Framework 4 (32-bit)
• SAP Crystal Reports version for Microsoft Visual Studio

I published the website to our Windows 64-bit IIS server but I get this error when I browse to the report: "CrystalReportsException: Load report failed."

I have the same CR runtime installed on the server - SAP Crystal Reports runtime engine for .NET Framework 4 (32-bit).  Do I need the Crystal Reports for Visual Studio runtime as well?  If so, I noticed when I try to install it, I get the error that "Visual Studio x.x needs to be installed".

Any thoughts?

Thanks for any help!
