Upgraded to the lastest SDK but reports not working.

Hi,

I have downloaded the latest SDK for VS2010 :-

SAP Crystal Reprots runtime engine for .NET Framework (64-bit)     13.0.14.1720

SAP Crystal Reports, version for Microsoft Visual Studio                    13.0.14.1720

I then installed the latest version of the runtime library's on Windows Server 2012 :-

SAP Crystal Reports runtime engine for .NET Framework (64-bit)     13.0.14.1720.

My web based project now runs on the new server with references to Crystal reports but when it comes to this command:-

ExportFormatType.PortableDocFormat, Response, False, "CIC Preview")

The report returns and exception:-

The system cannot find the file specified.

The strange thing is it steps over the report.load line of code because I have put traps in. I have also output the full path / filename it is trying to load and this is correct to.

Any help please as I need to transfer to the new server as soon as possible because the old one is being de-commissioned soon.

Thank you for any help,

Roger
