You should be able to install them right into Poser 7 because it's a completely different folder.

You can just install V4.2 into the Poser 7 runtime and you won't have any problems since she's not dependent on the V4 or V4.1 files.

You can try loading the P4 runtime as an external to P7 and see if you can load from there.  I haven't used P4 since I got P5 and don't even have it loaded any more.  I do know that P7 will load from my old P6 and P5 runtimes just by loading them as externals so it should work with your P4 runtime as well.

If you don't know how to load an external runtime, send me an IM and I'll explain how it's done.  It's not hard but it works wonderfully since I use 25 different runtimes.  I can load the ones I need to use without having all of the other content loaded as well.  The only stuff I have loaded into my P7 runtime is my V4/A4 stuff because they require the Poser.exe file.
