Actually, that sounds like the previous installer for V4. A newer one was released this year that lets you install V4 wherever you want. Then, most of the ExP installers will install to where V4 was installed. What you will run into is when the ExP installer wants both V4 AND the poser.exe file. You will need a file named poser.exe at the runtime level where V4 is installed for those. I have also found that for PP2010, these installers will not accept the PoserPro.exe; it needs to be named poser.exe explicitly, either copied from a Poser# folder or an empty file named poser.exe. My information here comes from a very recent reinstallation of V4 to get everything into a single location.
