maybe I could help but I need some more information.After number “50” should be some letter like P or N or S or PT.I need your e-mail to send Service Manual.
I’ve had the same problem with instalation of SIOS on the another PC with XP sp2.I’ve found that XP sp 2 does not support some older programs.I’ve tried to solve this problem using Compatibility Mode but it didn’t work.Finally,I’ve replaced XP sp2 with XP sp 1 .
