icacls Folder Permission Problem

Hi,

I am using icacls within a VBScrpt specifically to change permissions to a folder.

My attempts so far only seems to change the security of only the files within the folder and subfolders, which is only half of what I need.

I wonder if there is a parameter or anything that I'm missing that will change the security of the subfolders?

I am using this:

icacls "%ProgramFiles(x86)%\RKYV" /grant "Users":f /t /q

Any illumination would be greatly appreciated.

Many thanks.
