Sorted this out tonight.

Apparently the VooDoo card must be the primary from the BIOS for the tools to install.

Sorry to bring up an old thread, but I am a new Amigamerlin 3.0 user and I am having the exact problem described above.  Apparenlty the DLL's used for the tools cannot register themselves on my system.  I tried to add them manually from a command prompt using Regsvr32.exe but get an error there that it cannot be regitered as well.  So for me the tools will not install but the driver appears to work fine.

I've tried searching but cannot find if this problem has been fixed or even if anyone else other then me and the above user have the problem.

I did follow the instructions for installing.

1) remove any old 3DFX drivers (I did do this to remove my V2 boards and rebooted)
2) remove the noted registry entry and reboot
3) install the drivers using Driver Setup.exe and reboot
4) install the tools using setup.exe (this was a little point of confusion as everyone refers to running "isetep.exe" at this step, which does not exist in the 2 different downloads I have gotten.)

The only other thing I tried during this was a manual install of the drivers as recommended by the readme that cam with the installation.  And then reboot, install tools (ignoring errors), reboot, then install tools again but select repair.

End up still not working.

Last thing noted was after the tools install my ATI startup control would quit responding to the system?  No biggie I turned it off, but I wonder if these issues are related to multiple video card installation or an ATI specific card being installed?  or Maybe it's because I have a PCI model V5 5500 card?

Any help or ideas would be great, Here are my specs

P4 2.4c HT 800Mhz FSB
Windows XP Pro SP1 (all the latest hotfixes and patches)
512MEG Dual Channel DDR PC3200
ATI 9600 Pro 128MEG & V5 5500 PCI
DirectX9b, Catalyst 4.4, Amigamerlin 3.0 XP
SoundMax Digital 5.1


I can provide other info as needed.

thanks for any help.
