I'm trying to work on several different scenes at once with completely different elements. Not everything needs to have exactly the same features. I just need to be able to work on more than one document at a time rather than doing one, sending it to queue manager or background rendering and then working on another in the meantime.

I just need two different versions of Poser that can work independently of each other in their own right.

I've found the ini and xxml files but am not sure exactly how I should edit it and which one relates to which and what I should change all the settings to.

It must be possible to run PP2010 and PP2012 simultaneously since aeilkema mentioned earlier that he or she is doing exactly that and apparently not running into this problem.
