Quote - I had this problem with Bryce6 on Windows XP Pro 64 but it worked after I used 'Large Adress Aware' (LaaTiDo.exe  -> http://www.musikbanken.se/TechLaaTiDo.aspx). Maybe this little and free program helps in Vista or Windows 7 too (it was released for Windows XP 32bit to trick the 3GB limit, but it works also with XP Prof 64!) ?

Poser 7 and Poser Pro are compiled large address aware, so this tool won't change anything (at best). If they weren't, the Poser process couldn't even use 3GB, it would hit the 2GB barrier. See msdn.microsoft.com/en-us/library/bb147385%28VS.85%29.aspx for details.
