The old .exe installers do check for poser.exe if you choose Poser as the target application - it's best to get the most current version, which is in a zip (and can be installed manually or with the DAZ Install Manager) though choosing DAZ Studio as the target application will also get around the check for a Poser.exe (and doesn't make any difference to the files installed).

Which has always been an issue for Poser Pro version users, because the program doesn't create a poser.exe. Another way to get around that is to create a new text document in the runtime, name it poser, and with "show file extensions" checked, change the file extension to .exe.
