Rhino Plugin Failed To Load (Calc.Rhp)

Rhino locked up on me today after about 4 hrs on the same drawing. Was in the process of saving a named view when it failed. The drawing file had been the same size for approx 3+ of those hours.

Upon multiple reboots (Rhino showed in the program manager but was not visible) I received the following error. “Rhinoceros 6 Plug-In Failed to load”…“It appears Rhino failed to load the plug-in C:\Program FIles\Rhino\Plug-ins\Calc.rhp the last time you used Rhino. Do you want to stop using this plug-in?”

I only received this dialog box after the 3rd reboot.

Selecting “No” allowed me to get the program started.

I’m using:

Rhino is now working again as expected however without “calc.rhp”.

Any ideas on why Calc is no longer working in my version sr13 of Rhino?

Hello - did this happen once and go away or do you have to answer the question every time you start? And once Rhino is running, do the Calc and CalcRPN commands work?

-Pascal

I was only prompted to “not load” the calc.rhp file once.

Calc now shows as an unknown command.

CalRPN also shows as an unknown command.

Sorted here:

-Pascal
