This is what it says.

Sorry to hear that @sikim,

It sounds like a 3rd party plugin (CrossGems) is causing the issue, can you try running Rhino 8 in safe mode, it should load without plugins, and if that’s the case, it narrows down the issue.

4

how would I run rhino 8 in safe mode?

5

You should be able search “Rhino 8 in Safe Mode” in your windows search and it should be available to you.

Failing that, It can be found here
C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Rhino 8.

And failing that you could run this from powershell or cmd & "C:\Program Files\Rhino 8\System\Rhino.exe" /safemode

6

Ok so I figured out that CrossGems is causing the problem. I use crossgems all the time and this is the first time that it is causing me any problem. What should I do? Should I uninstall crossgems and try installing it back?

7

I would try uninstalling and reinstalling it, and ideally trying the latest version of it.

What version of Rhino are you using, and does their software recommend a specific Rhino Version?

8

I am using Rhino 8 at the moment, when I load up Rhino, it says that there is an update available these past few days and I have always closed it out. The software crossgems is built specifically for rhino 8

9

if you’re not on Rhino 8.7 I’d upgrade to that as well as upgrade CrossGems, if that still doesn’t work, we can try some other things next :slight_smile:

10

How would I upgrade Rhino 8? I try to upgrade rhino 8 when I open it, but it crashes before I could do anything.

11

I think a fresh install may be in order for Rhino then. Why don’t you uninstall it, then reinstall it fresh from this link
https://www.rhino3d.com/download/rhino-for-windows/8/latest/

12

If you have many custom toolbars and settings it might be worth backing those up first

13

i uninstalled crossgems and reinstalled it, it fixed the problem. Thank you!
