Hi Thanks for the replies. Sorry, I probably wasn't as clear as I should have been. In the link I provided, it says to integrate WMP11 using that WMP11 integrator tool listed in the post above BEFORE using nLite to slipstream SP3. So actually the sequence of events I'm doing is: Copy XP original files from CD to HD, open WMP11 integrator and point it to WMP11 install and XP directory so it can integrate, then open nLite and attempt to slipstream SP3 (which does work, just nLite says I should remove existing hotfixes, which there shouldn't be, before slipstreaming). But this process as I mentioned doesn't give me WMP11 after testing the nLite'd install in Virtual PC 2007. Any ideas? Cheers
