=====Problem=====
Rhino, Language Pack, or Help Media failed to install. The installer package may be corrupt or incomplete due to:
  * a virus detector left running
  * computer crashed
  * some other malware or program prevents the install
Also, reinstall or uninstall from Windows **Programs and Features** does not help.

=====Possible solution=====
  - Run this Microsoft Utility to: //[[https://support.microsoft.com/en-us/mats/program_install_and_uninstall|Fix problems that programs cannot be installed or uninstalled]]//.
  - Use the utility to remove your problem Rhino installer that is giving you the error with the utility. For example, with //Rhinoceros 5 Language Pack Installer (en-US)//. You can run the utility in manual or automatic mode.
  - When you have removed the problem installer with the MS Utility, proceed to Install Rhino, Help, or Language Pack. 
  - Open Rhino and run **ToolbarReset**. Close Rhino.
  - Reopen and test.
