Just install it, under >Program files or elsewhere.

Just do NOT install the runtimes there.

Put those under your user folders.

I think, it is the uppermost option during the content installation process.

I run Poser 8 and Poser Pro2010, on anything from a quadcore with 6GB RAM to a netbook (N270 CPU with 1GB RAM) without problems.

Windows 7 Home Pro 64 bit

Windows 7, 32 bit

Windows 7 Starter (on the netbook)

Windows XP 32 bit

Poser 8 became pretty stable after the SR2.1.

PoserPro2010 never gave installations or operational problems. (touch wood) 

Poser 1, 2, 3, 4, 5, 7, P8 and PPro2010, P9 and PP2012, P10 and PP2014 Game Dev
