Error 1904?

I keep trying to install AA CDC on my computer and it gives me an error message "Error 1904 Module. CWINDOWS\system32\cswsk32.ocx failed to register. HResult-2147220991. Contact your support personnel"

Anyone shed some light on my situation?

This happens when I try to install CDC

you need permision to register files on your computer, you dont have it so you cant install CDC

Right-click the file, choose run as administrator
