Hi all Help my head hurts! I have just fitted a new Motherboard, The MSI KT3 Ultra with onboard sound, my problem is I cannot load the drivers to operate the sound card, When I try I get an error message " 0x80070725 Description: incompatible version of the RPC Stub" I am running Windows 98. I do keep removing the sound drivers in device maneger but I keep getting the same error message. I also tried to update to the latest software from the MSI website, but strangly their update software does not cover win98 their forum is also down for an upgrade. Thanks in advance for any help.
