Remove all preferences/traces for a fresh re-installation

Rhino 5 on Windows 10 crashed almost every time when closing it. Must be something to do with the toolbars and/or panel layout.
This became pretty annoying, so I’m trying a fresh installation. I uninstalled it and deleted the preferences in

However, that alone did not cut it, because after the re-installation, the old panel layout is still there, but now all icons are missing from the toolbars!

So, there must be some preference/configuration files still floating around on the harddisk.
But where?

In other words:
Which files/folders need to be deleted to completely remove all traces of Rhino on the HD, to start afresh?


try ToolbarReset

I did already, didn’t work. I mean the toolbars are still broken.

Maybe this will help…


Hi Eugen - was there a crash report interface when Rhino crashed on closing? If so, did you send some of those in?


Hello! Thanks for the answers!
I’ve sent the crash report once or twice in the course of the last month already…
Interestingly the crash does not happen on my laptop.

Interesting also that Rhino still shows the same project shortcut icons in the splash screen after re-installation and obviously still remembers the toolbars - even after deleting the folder C:\Users…\AppData\Roaming\McNeel\Rhinoceros\5.0.
Where is this information stored?

Hi Eugen - see if renmaoing or deleting this key:
HKEY_CURRENT_USER\Software\McNeel\Rhinoceros\5.0\Scheme: Default

in RegEdit does anything good. Do this with Rhino closed and don’t mess with anything else in RegEdit unless you now what you’re doing…


It helped to delete the hivekey
before installation!
Toolbar layout and icons went back to default.

Thank you very much everyone!!
