I was running Speccy v1.03. Although Speccy ran, the analysis was incomplete with many entries saying Unknown system error. So I downloaded and installed Speccy 126.96.36.199.
When I run this version it crashes during analysis. I've attached a screen clip so you can see the state of the Speccy screen at the time of the crash and the APPCRASH details supplied by Windows.
I'm running Windows 7 Pro (64 bit) on an Intel Core i7 920 with 6GB RAM. There are two ATi HD4870x2 cards running four monitors.
