Rhino 6 CRhCommandManager error

Hello I have installed Rhino 6.3 and try 6.4 on a hp laptop mobile workstation with MS WIndows 10 Pro and when I run Rhino, I get this window error message


I installed Rhino 6.3 and 6.4 on other hp workstation and use it without problems, on this system I have Rhino 5 installation and MecSoft RhinoCAM 2018 for Rhino 5 if this can help to find a solutions for the error window message but I think that is not related.

Thank you


This is likely the same as 6.4 (italian language) - RhinoDotNetCrash

Ciao Massimiliano.

This is sorted in SR 6.5
The issue was limited to Italian. Got this error report from most Italian users.
One “ad interim” solution is to install English language pack.

Ciao Giuseppe,

“One “ad interim” solution is to install English language pack.” it means to install English Language pack for Rhino, after all menu and comands will be in English, right?


RH-45961 and RH-45962 are fixed in the latest Service Release (6.4.18130.19341)
