Several posts have referred to problems on installation. Having once installed XyWrite III+ without difficulty on my 286 PC, when I acquired my present 486 and tried to install XyWrite 4 (DOS) and XyWin, I got repeated hangups. My gurus in New Jersey put their heads together and discovered that I had to temporarily disable SoundBlaster 16 to make the Install work properly. Cheers, Eric Van Tassel
