Finding Rhino's Installation Folder
Windows only

Problem

You are putting together an installer for your Rhino plugin. You would like to know how you can, programatically, get Rhino’s installation folder.

Solution

Rhino 8, 7, and 6

If you are looking for Rhino 8, 7, or 6, then you can find the location of Rhino’s installation folder by looking in the Windows Registry in this location:

Hive:  HKEY_LOCAL_MACHINE
Key:   SOFTWARE\McNeel\Rhinoceros\<version>\Install

If you are looking for Rhino 8, for example, replace <version> with 8.0.
