I have an old Plugin that I need to use from a company that no longer supports it and it is not publicly released. It only works with Rhino 5.
I’m running 5.14 SR14 (latest download from website).
When I attempt to install it, using 32-bit, I get the error: “Rhino service release not specified”
When I attempt to install it, using 64-bit, I get the error: “Initialization failed”
My coworker is running Rhino 5 SR14 with the same plugin (same rhp file) and its working fine. He was using 64 bit.
I did check and it is not blocked (I did “unblock”). I’ve tried running rhino as admin.

Hi @enrico.ng ,
Try installing the latest 32-bit and 64-bit redistributables for Visual Studio 2005 and Visual Studio 2010.
Does this help?

Hi @enrico.ng ,
Do you know of this is a C++ plug-in or one written in .net?
— Dale
I dont see an assembly version so I am going to assume it is C++

Hi @enrico.ng ,
You might run it through the Dependency Walker to see if you can see what might be missing.

I used a different dependency program but it seems to have found all the dependencies.

Hi @enrico.ng ,
I’m afraid I out of suggestions. You’ve determined the plug-in is built for the 64-bit version of Rhino 5. I’ve had you install the C++ runtimes for VS2010 - the compiler used to build Rhino 5.0 x64 plug-ins.
I guess it’s possible the “Initialization failed” error is being generated by the plug-in itself, returning some other than success from OnLoadPlugIn. Maybe a licensing deal?
