hi,
please could you confirm me it’s possible to used 1 Rhino license on 2 computers with only 1 user.
thank’s
Yes. But not simultaneously. --Mitch
As a continuation of this question; I currently have Rhino installed on my laptop (which I use ALOT) and my desktop at home (which I never use).
I want to start using Rhino/Grasshopper at work, and it’s not always convenient to use my laptop (dataflow) could I uninstall at home then install at work and still be compliant?
Would still obviously only use either work desktop or laptop not-simultaneously…
Yes, no problem, you can install one license on as many machines as you want, as long as the license is not in use on more than one machine at a time. So you don’t actually need to uninstall Rhino from your home desktop.
HTH, --Mitch

Wooh! That’s even better! 
Thanks!
I also have Rhino 6 installed on desktop and laptop. I normally use the desktop, but I am taking the laptop offsite to use, but where I will be has very spotty internet. Do I need to log in to Rhino on the laptop before I leave the office (as I’ve been using the desktop) , or will the laptop installation work ok without the internet?
Two questions:
1- I now have also 2 computers (one user). Today I installed my version6 on the new one and rhino is telling me I do not have a licence. what did I do wrong?
2- I was planning to work without internet or at least only internet to start rhino and than cut off the connection.

Back in 2020, you chose to “Lock” your V6 license exclusively to a single computer, instead of choosing the “Floating” option.
- Use this document to remove the locked license from that computer:
Changing Rhino 8, 7, or 6 licensing method [McNeel Wiki] - Add the V6 license to the Personal Licenses" in your login account:
Rhino Accounts - Start Rhino V6 and choose the Login option
You only need an Internet connection once every couple of weeks to keep your floating license refreshed.
Any luck?
Hoi John, thanks for the explanation / advice.
I will try tomorrow and with some luck I can close this item.
Thanx
ehhhh, part one is done but at part two rhino is telling me my licence key is invallid …
and when i fill in my serial number it is telling me that I should use the licence key starting with RH60…
am i doing something wrong?
No, that’s not what the error message said.
It said the email address you’re trying to use is not valid for this license.
You are trying to use a hotmail address and you used a gmail address before, so our servers think someone with a different email address is trying to steal you license.
Assuming the gmail address is still valid, I’d recommend you add it to your login account so we know both addresses are you.
https://accounts.rhino3d.com/?controller=emails
Then you can use either address.
John, Thanx again.
Sorry for the wrong error explenation. English is not my native.
I added the gmail (did not know I used that)
IT works many, many thanks
Have a nice day
Your English is just fine and far better than my Dutch!
Cheers
