Problem
A message “Error 1406. Cannot write the value to the registry key \Software\Classes\CLSID\{(lots of letters and numbers)}\LocalServer32. Verify that you have sufficient access to that key or contact you support personnel. (1406)”
Cause
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{lots of letters and numbers} does not exist and writing the registry key is blocked by antivirus protection.
Answer
Disable your antivirus protection and try to install Rhino 5 again.
The settings in some antivirus applications are pretty complicated. If you don't know how to disable your antivirus protection completely, you can remove the antivirus application before installing Rhino 5. Reinstall the antivirus application after Rhino 5 has been installed successfully.
Note: This problem only happens on a Windows that has never had Rhino 5 installed. Those registry keys don't exist and the antivirus application blocks Rhino 5 installer from writing the registry keys.
If a Windows had Rhino 5 installed previously, even though it has been uninstalled, those registry keys still exist. Rhino 5 or the SR installer won't try to write those registry keys again and antivirus protection won't cause the problem.
