Manually Uninstalling Rhino 4.0


During the startup, install or uninstall of Rhino, you get an error message like this:

The feature you are trying to use is on a network resource that is unavailable.

Click OK to try again, or enter an alternate path to a folder containing the installation package '<filename>.MSI' in the box below.

This applies to Rhino 4.0 and Rhino 5.


The Windows Installer cache cannot find a file or registry key required for uninstall. This is a common problem caused by the Windows Installer Service. The best solution is to use Windows Install Clean Up to thoroughly remove the previous installation. After you clean up the previous install, you will be able to reinstall Rhino and get a valid install.
