Just installing an update, got a message telling me the programme does not have administrator rights or something similar.
The rhino executable now appears to have vanished from my system, folders etc all there.
How can I get it back, complete with the add-ins which were installed in it?
Thanks
simply download a new copy from here- https://www.rhino3d.com/download
Yes, as simple as that with the add-ins as well, everything just as I left it, quite impressed
