Actually, it doesnt like anyoperating systems except dos, win 3.1, and win 95 only. wont run on 98 or above. at least i ever got it too. So thats whats prolly wrong with that.
When you say Ripper5 doesn't work on Win98, do you mean not work at all or just won't extract stuff properly? 'Cause it runs fine on my Win98 (Original), but I can't be sure if the extraction routines are working the best.
