The Windows Installer cache cannot find a file or registry key required for uninstall. This is a common problem that is 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.
Manually remove Rhino and the Windows Installer registration for the product.
Note: you should only do the following procedures if uninstall fails from the Programs and Features section of Control Panel.
WARNING: The following procedure may result in registry corruption, and a 1402 error next time you install software. Only follow these steps if the above procedure did not allow you to install Rhino.
If you followed these steps and then got a 1402 error, these instructions may resolve the 1402 error.
