1. Get the imagehlp.dll file from the c:\\Windows\\System directory of a Windholes computer. Put this file in your dotwine/fake_windows/Windows/System directory. * (plese see information at the next tip)
2. Add the following lines to the end of your wine config file (dotwine/config) but before the '# [/wineconf]' line.
[AppDefaults\\\\Rhino.exe\\\\DllOverrides]
"imagehlp" = "native"
3. If you haven't already done so install Microsoft Internet Explorer. This is not absolutely necessary but it resolves the plug-in load failure / missing java engine error you may see at Rhino startup.
4. Kick back and start Rhino! (What follows no longer applies, since the menus WILL be created in Crossover 5.x) If a menu item / desktop shortcut was not created when you installed Rhino, you can go to your PATH_TO_CXOFFICEDIR/dotwine/fake_windows/Program Files/Rhinoceros/System/ directory in a terminal window and then type PATH_TO_CXOFFICEDIR/bin/wine ./Rhino.exe (the path to cxoffice dir is usually /opt/cxoffice or /home/YOUR_HOME/.cxoffice)
Rhino should start right up with no errors. If it complains that the XYZ plug-in could not load 5-6 times then says that a required plug-in could not be found: Rhino cannot run, it is not finding/loading the imagehlp.dll file, so check that you did the above correctly.
