I have had PowerDVD 6.0 OEM edition for some time, it worked perfectly fine. I recently tried to install PowerDVD 7.3 Ultra Deluxe. It wouldnt install because 6.0 couldnt initialise setup. I deleted all folders, files and registry keys relating to Cyberlink. Installed 7.3 just fine. I take note of the fact that Microsoft SQL server Desktop Edition needs to configure during installation (this was left behind from Sony ACID Pro). When I try to configure it, and I confirm, it hangs the whole system, requiring me to hit the reset button. I uninstall 7.3, reinstall 6.0. 6.0 Hangs after configuration. I think. I uninstall Microsoft SQL Server Desktop Edition and all other crap ACID left behind, (namely, although it is a bit grey, 'user-mode driver framework or something' and 'windows something compression'). Reinstall 6.0. Still hangs after config. Any ideas? I want either this to work or a comparable alternative to consider. I have AMD XP 3000+ 1gb pc3200 nv 7600gs gforce 2 chipset onboard ac '97 sound all latest drivers Any help would be very apreciated.
