Ok,

So I did as described here,
. Install WAIK SP1
. Install vLite 1.2
. Download Windows6.0-KB936330-X64-wave0 5 languages
. Select Business profile ( french student msdnaa version 6.0.6000.16386 ) after file copy
. Only enable slipstream and make iso options

Then the slipstream starts, and ... stops ( have to wait about 45min ). With Failed. No changes were saved as status. I can click Back, Next Exit but the sp1 integration doesn't want to work.

I tried to d/l a multilingual ( wave1 ) vista sp1 > same message.
I tried to choose BusinessN profile > same message.

Any help ? Thanks !

I have the same problem
I've installed the latest vLite 1.2 and after applying the service pack 1
(Windows6.0-KB936330-X64-wave1 becouse im from Poland)
The same message appers after 45-60 minutes
Failed. No changes were saved.

Im running on a clean install Vista Home Premium x64 without SP1
in RC 1.2 i diden't have this problem.

*edit
You know what? I remeber that when i was integrating the SP last time , SP was installed on my system
I'll install the SP1 first than try to integrate SP1

Solved!
You have to install SP1 first
also make sure that the vLite temporary folder
dosen't have any unicode characters like for example in my case "ŁÓŹĆŻŚ"

and you'll get a beautiful message
"Finished!"

I don't understand. I am getting this error message, and I have Vista x64 SP1 installed a long time back.
