How do I extract the msi from the Reader installation exe?

Usually when I want to extract the msi from the Reader installation exe (for Group Policy) distribution, I download it from get.adobe.com/reader/enterprise and decompress the exe using 7zip.   Then, I slipstream the msp file into it and I'm pretty much good to go.

Now, when I try to extract the msi, I get a directory full of stuff, but no msi at all.  I tried starting the installer and looking in C:\users\username\AppData (it works for Java) but it wasn't there.

Any idea what I'm doing wrong? Or is there a new way to extract the msi that I've missed?

Thanks!
