Sounds like maybe you did not unzip the patch into the HOI folder and select keep the directory structure.
 
You do not need to DL it to the HOI folder, you need to extract it to the HOI folder (ie. Unzip it to that folder)
Depending on what program you use to unzip it, you should select "keep directory/Folder structure/Names"
and also select to overwrite all files when prompted.
 
No problem, glad you got it to work.
