HELP!!! G400+Athlon+Biostar M7mka+SBLive: can't install LW3

[Sharkyz]

I just upgraded my system to an Athlon 600 an a Biostar M7mka. I switched
from a p3 450 installed on a QDI BX (no problem at all).
The problem is simple: I can't install LW3 (internet downloaded). No problem
installing LW2 from CD.
But when I try to instal the newer version I obtain that message:
"Setup could not detect any Sound Blaster card on your system. Please ensure
that your Sound Blaster Live! hardware is properly installed before running
this Setup program. Setup will now exit. "

According to Creative FAQ, I tried the following workarounds:

Check that Sound Blaster Live! is enabled under System Devices.
Use another mouse device.
Make sure PNP OS INSTALLED is set to YES.
Move the card to another PCI slot.

I tried everything (even leaving only the Live and the G400).No way. I have latest
bios/drivers versions and Windows98Se. I tried differnet Powerdesk releases.
Solutions.
Thank you a lot.

Athlon 600
