Slipsteaming 2K CD with SP4_EN

[Jeromie]

Hello. I am atempting to slipstream my 2k cd (cd label W2PFPP_EN) with my
SP4 (file name W2KSP4_EN). I have read http://old.bink.nu/bootcd and
http://www.thetechguide.com/forum/showflat...&fpart=all&vc=1

Everything looked good until I tried update.exe -s:H:\2k.cd.info\W2PFPP_EN
I get the error "Integrated Install Failed. The Language type or platform for the
destination and Service Pack 4 must be the same."

Both are english and are W2k.

Any idea as to what I am missing?
