algorithmic modeling for Rhino

So I had to re-install Rhino and Grasshopper to solve the issues I was having with grasshopper freezing. This worked great except, I am pretty sure Rhino 5 64bit is now in a different location which prevents the Visual C# plugin from working correctly.

I figured here was a good place to post this because David and Giulio are both pretty active here.

I have two problems:

1) I cant create any new plugins. Every time I try, it gives me the error below.

2) I can't debug any scripts on 64-bit. 32-bit works fine, but I get the error below when I try to debug with 64-bit.

Thanks for all the help!

Can you verify that C:\Program Files\Rhinoceros 5.0 (64-bit)\System\Rhino.exe is indeed missing? If it's not there, where is it?

For some reason it is here:

C:\Program Files\Rhinoceros 5.0\System\Rhino.exe

Notice the folder isn't labeled as (64-bit) even though that is the 64 bit version of rhino.

Hmm, maybe we changed the installer at some point to use a different folder. Anyway, it seems that changing your debug target path to the new location should fix that. If you have VS Express then you'll have to change the path inside the *.sln or *.csproj file using Notepad (I can't now remember exactly where the debug target is saved).

For existing projects, edit the csproj file with notepad. Down at the bottom, change:

<StartProgram>C:\Program Files\Rhinoceros 5.0 (64-bit)\System\Rhino.exe</StartProgram>


<StartProgram>C:\Program Files\Rhinoceros 5.0\System\Rhino.exe</StartProgram>

I will look and see if I can get the wizard to allow you to create new projects, that still isn't working.

Well figuring out how to fix the Plugin to create new components is way over my head. I will have to wait and see if Giulio can make any adjustments necessary.

Thanks for the help David!

I know that Steve if fixing this as we speak, but there's an already-made project here

in case you cannot wait.

I hope this helps. McNeel will update the current wizard soon with the additions shortly otherwise.


I appreciate all your help! Mcneel and its community really goes above and beyond, and does a great job being embedded into its community of users. Everyone is always helpful, engaged, and quick to respond. I wish some of the other software leaders in the AEC industry would take notice. 

Also, while we are updating the wizards to 2012 does it make sense to just bump them all the way up to 2013 now that it is out? (No pressure, just a question from an uneducated wizard maker)

Thanks for the fast help Giulio and David. You guys rock.
