It’s a Rhino 5.
I’ve just installed Rhino, there’s no plug-ins…
As soon as I start Rhino the pop-up appears on screen and stop me from doing anything.
So I need to close it by task manager.
First, do you have the latest service release (SR 9)?
Hmm, looking at this again - I wonder if this is the context Help that is enabled automatically on install that is causing a problem with a non-English language. Can you try starting Rhino in SafeMode and see if Rhino starts without the error message?
Edit: I have a possible solution if this is the case.
Even a normal user should be able to start Rhino in Safe Mode (not Windows):
In Windows 7 or earlier, Start button>All Programs>Rhinoceros 5>Rhinoceros 5 in Safe mode.
In Windows 8, Start screen>Right click near bottom, choose All Apps>Rhinoceros 5>Rhinoceros 5 in safe mode.
Start Rhino in Safe mode. Type CommandHelp and then press Enter at the command line - do this only once!
Now, close Rhino.
Try starting Rhino in normal mode…
If that works, it means there is a problem with the Command help panel it tries to access a web page to auto update (I think) and there is a problem with non-English languages - at least there has been in the past… Running CommandHelp once will shut the panel (I don’t know of any other way if Rhino is frozen).
If the above procedure does not work, then there is something else wrong…
