we manage to distribute the 2010 installation with

1. doing a admin image
2. NAL with distributionscript: <AdminImage Path>\setup.exe /W /Q /I <AdminImage Path>\<deployment name>.ini /Lang en-US

worked fine... but now we got 2011... tried the same but get error. The installation line above works when running manually as system or administrator. But not when distribution from the NAL

get this log file
