I have window 98 SE and put in a Sound Blaster 16 PCI sound card, I had a 64 bit sound card before. My sound card stopped working so I installed a the new sound card. I removed the old driver and installed the new one. I also accidently deleted a program called GT interactive. My sound card is not working. When I try to reinstall, after it tries to update windows drivers, it gives me the message the file you are trying to open is already in use by another program, quit the program and try again later. I click cancel and it again will try to update windows drivers and this time return with the message: setup could not detect any Sound Blaster harware, Yet it had detected it at startup. The card appears to be firmly in the PCI slot. When I try to use programs that have sound such as my scrabble game it either gives me the message failed to initialize sound engine, or sound cannot open audio device another program may be using it. I don’t know why my other sound card stopped working it was not very old. What does the GT interactive program do? I’m thinking it is related to my scrabble game. Could I have a compatability problem? I have a 16 bit sound card and DDR SDRAM memory. What do you recommend.
