Well the only other ting is to try it on another computer. In 95 my squadron got 16 brand new computers, my shop got 2 of them (all the same). The two in my shop would not import a text file into Access the other 14 would. Reloaded multiple times using various install disks etc. No help. Finally brought a working machines reg key over and even though they were the same looking at them it fixed the issue. Reload the OS etc and it was broke again. Point being computers are way more different then people think as common belief is that if it runs on one it will run on all, especially if they are the same config. You may be unlucky and have a computer that cannot run Poser 11 no matter what you do.

Poser 5, 6, 7, 8, Poser Pro 9 (2012), 10 (2014), 11, 12, 13
