DirectX 7 and Viper 550



Can anyone please help me!!!
I want to uninstall DirectX 7 and i dont know how.
I cant uninstall it from Add-Remove Programs.
I have problem with Viper 550 AGP-hardware 3d,he wants DirectX 6
to work.
All this with Windows 98 SE and the newest drivers for this



It must be something with Win98 SE, since I run DirectX 7 with Viper 550 and no probs on Win98. I have no idea.
