Hi, pakled.

Adding new runtimes to P5/P6 is a doddle:-)

I assume you've installed P5 into a new folder (eg: Program Files/Curious Labs/Poser 5, or anywhere else for that matter, just don't try to instal it into your P4 folder - that would probably result in disaster).

Open P5. Open ANY library. Navigate back up as far as you can go (via the "bent arrow" at the top of each library).

You should end up at the "top level" with (probably) 2 entries in it, one labelled "Poser 5", the other labelled "Downloads".

Either click on the "+" sign at the bottom of the Runtimes page, or hit the little triangle next to the name of the library you originally opened (it should be there, right near the top) an select "add new runtime" from the drop-down menu.

In the pop-up dialogue, navigate to your poser 4 runtime, highlight that and hit OK...
Your P4 runtime will be added to P5's list of runtimes:-))

NB - this will add (a "pointer" to) ALL of P4's runtime stuff - you don't have to do it for each library...start from any one, you'll get the lot (including geometries).

Cheers,
