Start vLite: hangs after selection Vista version

[fritsspits]

I've installed vLite on my computer with Windows Vista SP 2 and I want to make a slipstream for Vista with SP 1.

After starting vLite and making the selection of the Vista version (in my case Home Premium) the program VLite says 'loading' and shortley after that the program doesn't respond any more.

I've tried several things: disabled virusscan; the Temp map is C:\Temp; the map with the Vista installationfiles is also on C:\VISTAvLite. Starting vLite in safe mode (F8) gave the same problem: after selecting the Vista version in the map with the installationfiles vLite respond with 'loading' and then hangs.

Who can help me?
