I encounter error when im trying to patch red alert2 yuri's revenge error message "missing or invalid registry/INI entry" when i press okay patch "searching for system updates" another window pop up Find HKLM.SOFTWARE\Westwood\Yuri's Revenge.Install Path what will i select?

I select some files and the error appears "Old Files not found. However, a file of the same name was found. No update done since file contects do not match."

What is that means

Hope you can help me.

Thank you;
Rommel.
