I use VB for this type of automation but I've used AutoHotKey in the past & it will do the job. If you search, there are probably a few macro builder utilities that might make the process easier than AHK not sure. Creating your own is the only way to really handle the various installers. Ideally, you'ld probably want to read the version information of the .exe to determine which installer it was. but that's getting pretty involved.

Usually, I have the Daz installers install to a working folder as others have mentioned. The isntallers remember the path between installs, at least for me. I just tested it and did a scan of the registry. I cannot find where the path is being stored though, odd.

 I don't know if anyone mentioned this free utility - might be worth a try.  "Windows only macro that automates the installation of Bitrock installers from DAZ."
