Android SDK folder stays read only

After downloading/installing Android SDK, it put the files/folders here: C:\Program Files (x86)\Android\android-sdkif I right click on the parent folder, Android, I see that it's readonly. I unchecked readonly, and I got a prompt saying, "You will need to provide adminitsrator permission to change these attributes". I clicked Continue. It then seemed to run thru that folder and all of its children, applying the new non-readonly attr.
But when I right click on the Android folder and go to props again, it says it's readonly again.

Win7 has a lot of access problems when you install some programs in the Program Files(x86)

Uninstall the android sdk and install it in C:/ for example, it will work.
