I’ve been searching all over the forums, but I just don’t find an answer concerning compatibility between WIP and .rhi files.
Anyhow, I would like to install the Clipper plugin in WIP. Is that possible?

just double click it and it will install
but some plugins will only work with rhino5
Only plug-ins built on the RhinoCommon SDK are checked for compatibility when you try to load them in RH6. If the functions that are called by the plug-in exist in the current (RH6) version, the plug-in will load. In all other cases, plug-ins compiled to older Rhino versions will not work.
More info in this thread:
Then it will install with version 5. How do I make WIP at least attempt installation of the plugin?
Hi Felix - here this appears to install a version for 6.

-Pascal
here not
@feklee whilst Rhino WIP does indeed load compatible, outdated RhinoCommon plugins I only just got round to tweaking the Rhino Installer Engine (rhiexec) to allow V5 plug-ins to be installed for Rhino WIP. I also added some extra information to the dialog, as seen in Pascal’s reply above. Unfortunately last week’s WIP was delayed but hopefully we’ll get one out today/tomorrow which will include the new version of rhiexec
. If you can’t wait, then rename the .rhi to *.zip, extract it somewhere and drag-and-drop the .rhp into Rhino WIP to load it!
BTW, @feklee - the plug-in did not actually load in V6 - at least not here in our daily builds, so you may end up needing to chat with the plug-in developer.

Thanks for letting me know, Pascal. I contacted the developer now.
Sure, I’ll have a look at it this weekend to see if I can make a V6 build.
Ok, there’s a new version up at food4rhino
Tried it out, and reported as a comment on: http://www.food4rhino.com/app/clipper-grasshopper
It could be that I discovered a small Rhino bug:
Dragged the .rhp file into WIP, got informed that it’s blocked.
Unblocked the file using the Windows Explorer file properties.
Dragged the file again into WIP, and again I got informed that it’s blocked.
In the end I restarted WIP, and then it worked.
That was quick! I successfully installed it, as follows:
- Renamed
clipper-022-rhino6.rhito:clipper-022-rhino6.zip
- Copied the contents of the zip archive to:
C:\Program Files\Rhino WIP\Plug-ins\Grasshopper\Components
- Unblocked
ClipperPlugin.rhpvia file properties in Windows Explorer.
- Restarted WIP. (necessary, or else it would still report that the rhp file is blocked)
- Dragged
ClipperPlugin.rhpinto Rhino WIP.
Now for testing, which failed:
- Started Grasshopper.
- loaded a file that uses PolyOffset, and which works in Grasshopper for Rhino 5. In Grasshopper for WIP, that component gives me an error message: “1. Solution exception:Could not load file or assembly ‘ClipperTools, Version=0.0.2.1, Culture=neutral, PublicKeyToken=null’ or one of its dependencies. The system cannot find the file specified.”

Replying here, it’s a bit easier:
Possibly the ClipperTools.dll are still blocked, can you check? Both grasshopper and rhino need this file. Also, possibly there’s still an older version in another place. I’ve just released a new version (0.2.3) that is also built against the newer grasshopper (although the other one should also work).
RH-37982 is fixed in the latest WIP
Just to let you folks know… starting with the WIP that went out today, the Rhino Installer Engine will install V5 rhinocommon plug-ins for Rhino WIP (as seen in Pascal’s reply above). 
These plug-ins get checked for compatibility with the RhinoCommon SDK the next time you load Rhino WIP. As it turns out the compatibility checker was being a tad over-zealous but, as Brian notes above, that’s now fixed!
@arendvw Sorry you had to go to the trouble of re-releasing your plug-in. I hope that these changes will save other developers from having to re-compile plug-ins just for the sake of re-compiling! Although I see you took the opportunity to do a little maintenance 
Thanks for the update!
On a related compatibility note: do rhi files for mac require anything different? Or should they be ok if they do not require any native libraries?
That was it, thanks!
@arendvw Sorry for the delay.
Please take a look at the guide to plug-in installers in Rhino for Mac. You’ll notice that things are a little bit different between platforms. If you also add the GHA to the RHP bundle then Grasshopper will load it.
