Latest install won't open

Same thing happening here - installed the latest .msi and Rhino 6 opens with no plug-ins loaded, including toolbars, etc. Yes, it does look like it thinks the license is invalid or expired… Debug log sent via PM.


Hi Brian
Below the splash screen
Ciao Vittorio


Were any of you ever prompted to validate your licenses? It looks like both Willem and Mitch have Rhino in a state where it thinks the license has not been validated, and the validation grace period is expired, and it isn’t showing the validation dialog box. Weird.

Not sure if by “any of you” you mean just those with misbehaving Rhinos, or everybody, but my install is working I was prompted to validate on the original install of v6.


Hi Brian,
Yes, I validated immediately on first install and it was accepted…

On the original install of RH6, yes. After uninstall and reinstall, yes. But not when updating.

I tried the thing with the registry but that didn’t work. The 2 keys were already there but in 0 value. I put them to 1 and launched Rhino but no text file was created at that location. It is possible that that has something to do with there being 2 “My Documents” folders with one being sync’ed to a network location…

I can not remember if I was ever prompted to validate. However, I’m sure if I was prompted I would have done it immediately and not dismissed it.

As for the latest re-install, I did not receive message/prompt dialog.

i’ave send it per private message

Same as what Willem said, Validated when asked the first time, not asked since then.

Just uninstalled and reinstalled. No change, toolbar still missing and plugins not loaded.

hi @brian, same here after reinstall, no toolbars or pluins.


New WIP (yesterday) didn’t fix anything… :frowning:


On my workstation it refuses to open. It just crashes.
When opened in safe mode I get to the “do you want to install the toolbar.rhp” question and click Yes to that three times and then it crashes. So toolbars seems to be the issue.

A shot in the dark, but could it be language related? I am Norwegian so I have some of the letters “æ”, “ø” or “å” in some of the paths on the computer.

My system is entirely in English… --Mitch

By the way, I manually downloaded the latest build on my laptop now, and got the same “expired” message, with no toolbars.

Jep you just have to accept your machine is disabled for the WIP right now.
We just have to wait for @brian to get us fixed up.


Yeah, it turns out this week has been full of broken-ness. The license validation system has been misbehaving for much of the week, affecting a large number of Rhino 5 users. I’ve been focused on fixing that. Once that, and a Rhino 5 SR10 release candidate is out, I’ll get back to fixing this. Sorry to leave you without a working WIP for so long.

Those of you who cannot run Rhino WIP: how many of you have Apple iCloud installed on your computer?
