I know you can have different versions of Poser installed on the same system at the same time, but I don't know if this is true of all versions or if the order of installaton might be a factor.

I currently have Poser 7 installed. I would like to install my old versions, i.e., 6, 5, and perhaps even 4, for testing and compatibility purposes. Has anyone done this? Has anyone done this in something other than the natural lesser-to-greater order?

Were there any tweaks necessary? And does everything work okay?

Thanks.
