How to send a crash report
  • Can you repeat the crash? If so, the developers would like to get the specific details needed to repeat the crash. A repeatable problem is the only good way of finding and fixing problems in software.
  • When Rhino crashes, if there is enough memory available, the crash reporting system starts. Enter your email address and describe what you were trying to do when Rhino crashed. A short list of the commands you were using just prior to the crash can be helpful.
  • If possible, check the box to send your 3dm file with the report.
  • If you include your email address and a description, your report will be analyzed by a human. If you don't include your email address and a description, we will use an automated process to analyze the crash report.


Rhino won't start
This problem could be bad display drivers or a bad plug-in. Here's what to do to narrow it down.


Why use Safe Mode?
A shortcut in the Rhinoceros Program group opens Rhino in Safe Mode. Safe Mode is a troubleshooting tool that blocks OpenGL and plug-ins from loading. In Rhino 5, it also blocks loading of toolbars and the Render Development Kit plugin (RDK). Normally, answer “Yes” to loading them. Safe Mode is a troubleshooting tool and is not intended as a working mode.

Installing Rhino on two computers
You can install Rhino on more than one computer. Your license agreement allows you to install your Rhino on all of the computers that you directly control, provided that you run your Rhino on only one computer at a time. You cannot “loan” your Rhino to a friend.


What previous version info do I need to install a Rhino upgrade?
There is no need to install previous versions, just have the key codes ready.

The Rhino 5 Upgrade installer will install if one of the following is true:

  1. Rhino 4.0 is installed
  2. Rhino 3.0 is installed
  3. Rhino 2.0 is installed
  4. Rhino 4.0 key code is entered during installation
  5. Rhino 3.0 key code is entered during installation
  6. Rhino 2.0 key code is entered during installation


When I try to open a file, I get an error message about something being unreadable
Here's how the system works. there are two parts:
  1. Autosave. If you have Autosave turned on in Rhino, then temporary files are written to the folder specified in Options, and a flag is set that Rhino is running. When Rhino closes normally, it deletes this autosave file and Rhino clears the flag. If Rhino crashes, the flag was not cleared and the autosave file still exists when Rhino starts the very next time. In that event, you are warned that Rhino did not close properly and you have one chance to save your work from the autosave file. If you say no, you lose the file.
  2. Backups. As of V4 SR7, we added an automatic backup feature. If the feature has not been disabled, when you open an existing file, the changes in this new editing session are saved to a new copy of the file and the existing file you opened has “.bak” concatenated to its name and the file is left in the same folder.
    1. Rhino 5 now makes *.3dmbak files and has a file type listing to open them.
    2. For Rhino 4, use your file Explorer in a List or Detailed view, with Windows Folder Options set to show the file extensions for known file types, and rename the file from <filename>.3dm.bak to <newfilename>.3dm. Then you can open it like any other Rhino 3dm file.


When I installed Rhino, I checked the option to use the Zoo, but I don't use the Zoo
On Windows Vista or Windows 7, delete all the files in: C:\ProgramData\McNeel\Rhinoceros\5.0\License Manager\Licenses.
On Windows XP delete all the files in: C:\Documents and Settings\All Users\Application Data\McNeel\Rhinoceros\5.0\License Manager\Licenses
  1. Restart Rhino.
  2. Enter your key when asked.
Note: On some systems, instead of the “\All Users\” folder, the path may be your “\Domain\” log in name.
