Do you have the V7 WIP installed?
If so, you’ll need to update that too to get the newer Rhino Installer Engine application in place.
No. I use Rhino 6.5.
This is Not a 6.5 fix.
If you have not installed the 6.6 Service Release Candidate, it won’t work either.
My point was if you have the Rhino V7 WIP installed then the Rhino Installer Engine has a newer version so the 6.6 update RHI engine will not be replaced.
If you Never installed the V7 WIP, then I don’t understand why this didn’t work for you.
It would certainly be helpful, considering the subject of this topic (offline), if you included a direct link to the Service Release Candidate download file.
This is “work in progress.” Internet HTML files work much better.
