Had version 4300303 installed, which worked under XP, but didn't work under Win7. Saw update on DT site, which like to work there so I downloaded it and tried to update XP first and then try under Win7.
Installation began and then asked restart. Restarted and when Explorer was up system unexpectedly crashed with Blue Screen INVALID_PROCESS_DETACH_ATTEMPT (6, and all parameters zero)
Restarted computer. System up without any problems. DT wasn't installed. Started installation again - almost immediate Blue Screen.
Restarted Windows, turned off everything that could imagine - firewalls, HFS, uTorrent. Uninstalled sptd hidden device and fake IDE (both visible with Show Hidden Devices option selected). Restarted Windows, started installation - Blue Screen.
Restarted, downloaded SPTD 1.58 from DuplexSecurity. Run it - it says that 1.58 is already installed. Chose "Uninstall", restarted. Reinstalled SPTD 1.58, restarted.
Run DT setup - Blue Screen. F**K!!! As you probably guessed I'm despaired.
What I gonna do? Do you need kernel dump/debug prints/something? Some magic switches in boot.ini?
