When I clicked "save" in the wizard, it created AcroPro.mst and when I did Generate Transform, it asked me for a filename so I called it myInstall.mst.
I tried using both mst files on separate installs, and they both installed successfully, but both of them required the sign-in on first run.
After a few attempts, I deleted and started with fresh source files, and am only using AcroPro.mst currently.
