Rhino 6 keeps crashing (text/dimensions)

It always crashes when I do one thing. If I go to the properties tab for a text or dimension (text or linear dimension) and click on anything it instantly crashes. I just installed Rhino WIP and it also crashes when I do the same thing. This didn’t use to happen and it started happening without updating Rhino, so it’s something else causing it but i have no idea what.

I thought it happened on my other PC as well but it actually doesn’t. I’ve installed every windows update (1903).

Hello - are you sending in the crash reports?

Can you please run SystemInfo in Rhino and post the results?


Ok. Yes I’ve sent some reports. It usually crashes when I click on any options that has to do with text or dimensions. It also crashes if I go to “Tools -> Options -> Annotation styles -> Edit” and try to change anything. I can’t modify text styles in any way. Also going to “Document User Text” and randomly clicking on the panel to the right causes Rhino to crash.

If I try and change settings for anything else it doesn’t crash. (so far). I also have Rhino installed on a newer PC with a 3700x and RTX 2080, same version of Windows same version of Rhino. Rhino does not crash on that PC. But I use this PC for work (laptop) the other is my Desktop at home.

It only started crashing quite recently. I remember changing text settings with no problems maybe a couple of weeks ago. That was just days before some windows updates got installed. (KB4515384, KB4514359)

Try this:
In Rhino Options > Plug-ins, change the list filter to plug-ins that do not ship with Rhino.
Disable all of them.
Close and restart Rhino.
See if you can repeat the crash.

If the crashing is gone, enable one of the plugins, restart and see if it comes back.
Continue until you identify the problem.

If Rhino crashes even with those extra plug-ins disables, then it’s something else.

Hello - thanks - I see there are a few of the same crash from you in the last week or so. I don’t know what that gets us for now, but it’s at least possible the reports will give the developers enough to help out.


KB4515384 appears to be sporadically problematic, including at least one Rhino installation: Windows Update KB4515384 kept Rhino from starting up

If the crash dumps don’t point to a quick solution, it may be worth uninstalling KB4515384 to see if that cures your problem too. If it does and you want to prevent Windows Update installing the update again, there is a link in that thread to guidance on how to do so.


I tried uninstalling windows update KB4515384 and that worked, it doesn’t crash anymore. A bit odd though, my other PC has that update installed and it works just fine.

That worked, no more crashes after uninstalling KB4515384.

Yes, it’s fine on my pc and my laptop, AFAIK. Worst sort of bug to track down because it only affects a small percentage and you don’t know what other factor is involved.

Glad you are back in action, but don’t forget Windows Update will reinstall it unless you lock it out as per the link in the other thread.


Thanks for letting us know -

@jeremy5 - thanks for that.


Well… same thing is happening again and NO, KB4515384 is not installed, I did hide it with that utility. Some other windows updates have been installed since then. I guess they added the same crap in another update.

EDIT: I just tried uninstalling the latest update that windows had installed, think it ended with 389. So the problem that was caused by KB4515384 is now in the update ending with 389 (maybe KB4515389). Yay for Microsoft. So it doesn’t even help if you hide the updates that caused issues for you, they’ll make sure you install them one way or another.

Well at least my issue is fixed again, untill windows reinstalls it in another update that is.

…and now windows update KB4524570, that was installed 18.11.2019 (today), reinstalled whatever causes this crash… again. I guess I’ll just have to keep uninstalling windows updates once a month or so.

Hi @Mikael_Liback,

If you want to bite the bullet and try to discover the root cause of the problem rather than continue the windows workaround then I would suggest starting by looking for differences between the PC that is OK and the one that is not.

Are they both Windows 10 Pro for example? Do they run the same antivirus? Is there any software on the bad one that isn’t on the good one? Are there device drivers on the bad PC that aren’t on the good one? Is the firmware up to date on the bad PC?

Look at the Windows logs around the time running up to a crash: any error messages peculiar to that time? Any error messages that stop after you uninstalled an update?

You have run system information for the bad machine, run it for the good one and see what, if anything, is different.

Wherever you find an error message, or a difference between PCs search on the internet for it in conjunction with references to the Windows Updates from KB4515384 onward.

This could be a long and frustrating process (or you could get lucky) but the Windows ecosystem is no longer geared up to deferring updates indefinitely.

Ultimately you may need to make sure you have good, current backups of the bad PC and wipe the disks, disconnect any unique peripherals, update the firmware and bios if necessary, reinstall Windows from the latest image you can find, run windows update, including drivers, then reinstall Rhino. If that works OK then reintroduce peripherals one by one, checking after each that Rhino still works, then do the same with software, before finally restoring your data.

Whatever you do - good luck!
