I'm not kidding. I'm really trying to install this "state of the art" piece of crap video card in my computer. I've sold my video card and until my Gainward Geforce3 Ti Golden Sample arrives, I'm stuck with a 16megs Vanta. I can't make it work. I've tried Detonator 43.xx, both using the install kit and the advanced installation where I provide the path to the inf file. When I'm installing it using the distribution package in the normal way, it says in the end that installation is ok and I'm prompted to reboot, which I do, but the drivers won't install, all I get is the VGA drivers. When I'm doing an advanced installation, the error i get finally is "An error occured during the installation of this device. The data is invalid". Of course, I've uninstalled the previous card (also Nvidia, but a Geforce2) and I've cleaned the system with Driver Cleaner. One thing I could think of is a problem with VIA drivers. I couldn't find a link for VIA Hyperion uninstall, so I ran the installation package again and chose uninstallation of the drivers. It worked, but Vanta did not install this time, either. Scratch that, I've even uninstalled everything VIA from Device Manager and tried the Detonator install once more. No such luck. I get the unsigned driver prompt every time I try to install, I click "continue", but the driver won't install, no matter what. I'm thinking maybe an application is locking my current VGA driver, but I'm not running any. I quit Riva Tuner and Powerstrip, but it did not help. Maybe it has something to do with AGP. But it doesn't work with Hyperion, it doesn't work without Hyperion. What else to try? I'm lost... Pissed off really bad 'cause VGA mode is not fun Any ideas how to fix this?
