I downloaded from Vogons Driver Library "Sound Blaster 16 DOS Installation Disks" to use on a Sound Blaster Vibra16C in Dos but If I copied all three folders to my HDD (CSP, Install and PNPCFG) and tried to install CTCM first from the PNPCFG folder it keeps asking for the location of some files so I type in the location and I get in a loop so I quit it and by accident I tried it from a burnt CD disk and it went smoothly no probs, I am wondering why this is the case I have done this a few times from scratch and its the same every time.
