SSC dll 32 bit and 64 bit filenames

Hi, Paul and everyone else at “NREL SAM”I hope you are all safe from COVID 19. Here in Perth, Western Australia we are very lucky, as we only have a handful of active cases. I have a running 64 bit C# (visual studio) application that is accessing the PVWatts7 API.I used the code generator to get started: It output these dll’s:

• ssc.dll
• ssc64.dll

It had these 2 imports within the example C# language wrapper:

• [DllImport("[b]ssc32.dll[/b]", CallingConvention = CallingConvention.Cdecl, EntryPoint = "ssc_version")]
• [DllImport("ssc64.dll", CallingConvention = CallingConvention.Cdecl, EntryPoint = "ssc_version")]

I want to have both 64- and 32-bit installation options. When I compile for 32 bit, the example program looks for “ssc32.dll”, however I do not have it. Is the ssc.dll the 32-bit version, and I should just update the import statements to this name or rename the file?Thanks Mark

Hi Norman,

We discontinued support for a Windows 32-bit version of SAM and SSC as of 2020.2.29. It took some effort to manage dependencies for both versions, and given Microsoft's waning support for 32-bit versions of the latest Windows products, we decided to only support 64-bit SSC.

Best regards,
Paul.
