Hi I do not think this is an Xpcreate problem but you may be able to help me. Original CPTR, 2 years old running XPPro, Athlon processor, it works. Title in program - XPCREATE 20 Aug 2005. Created two slipstreamd CD's 16-10-2005 and 9-11-2005. All OK. New CPTR, XPPro, Gigabyte GA-81955X Royal Mobo, Intel D processor and other higher spec devices like Graphics, SATAII drives etc., it does not work. Error messages: XPCPRVAR is not recognised as an internal or external command. XPCTVARS is not recognised as an internal or external command. XPCPRLOG (5 times) is not recognised as an internal or external command. BBIE is not recognised as an internal or external command. Error cannot find XP source Value CDSOURCE\I386 Ecode 1001 I turned of the AV software but still the same. Any ideas
