Hello,
On my Vista Home Premium (mobility hd 4570 512MB, reported as 4530 series) the driver installer goes through the motions of installation for quite a long time, never gives me the "flashing" monitor and apparently forgets to install any dlls, as the samples complain about all of them. At first I thought it was a failure to install dlls, but now I think the dlls follow the graphics driver and it never gets installed.
On Ubuntu 8.10 where I previously had the Stream SDK running succesfully, I can compile the new samples but they are segfaulting. The display driver gives me the "this is beta and will expire" warning, which is annoyingly large, what is AMD thinking! I thought it would go away or I would find the switch in the docs to turn it off, no such luck.
Cheers!
