Hi, I'm trying to install this driver on my Windows 8.1 machine. I have disabled driver signature enforcement but it still won't work. Installing using the Creative/Auzentech installer, everything seems to go okay but there is no prompt "are you sure you want to install this driver from whomever". After installation is finished, in device manager the sound card shows up as "there are no compatible drivers for this device". If I then try to install manually (still with signature enforcement off), by doing a "update driver" then "browse my computer for driver software" and pointing it to the PAX_AZT_PRELUDE71_2013_V1.00 folder where I extracted the 7zip file, it starts to install the drivers but then comes up with "Windows found driver software for your device but encountered an error while attempting to install it - The system cannot find the file specified." Seems I'm not having much luck with sound cards lately. Any ideas anyone?
