I am getting the same error, and I am installing it with the DVD.
At the end of the install is says:" Execute: "D:/software/PhysX_9.09.0408_SystemSofware.exe" /q
The error dialog box:
The text says:
"The program Installer.exe has encountered a serious problem and needs to close. We are sorry for the inconvenience."
"If this problem is not present under Windows and has not been reported yet, you can report it at http://bugs.winehq.org."
I am running Crossover Games version 8.1.4 on a Macbook Pro running Snow Leopard 10.6.2 with 4 Gb of ram. A month ago or so I tried running Dragon Age with I believe Crossover Games version 8.0 and it worked with the 2d but not with 3d. Perhaps I should try version 8.0 again and use minimum settings.
-- Which version of Crossover Games plays best with Dragon Age? --
** EDIT: The game starts and runs nice and smooth on my Macbook Pro running Snow Leopard, 4 gigs ram, NVIDIA GeForce 8600M GT, even though PhysX did not install. I just can not have the Graphics Detail higher then the low setting.
Have a great day!
