Dear folks, thank you for the fast reply. My first tests were... VistaSp0-Audit Mode-SP1-reboot-SP2-reboot-generalize (RTM from 28.Apr.2009) Because this results in the error, my second tries were... VistaSp0-Audit mode-SP1-reboot-generalize Even the same error... The show must go on, so I installed... VistaSP0-Audit Mode-NO CHANGES!-generalize After that I used the command... imagex.exe /compress maximum /flags "HomePremium" ......... "Windows Vista HomePremium" Consider, there was nothing changed on my last try but the error is the same if I would do so. I forgot to mention that the command imagex.exe -info....... results in the same overview my original purchased install.wim results in. vLite 1.2 can open my original VistaSp0 without any errors, but not the "homemade" version I have no further idea. @MagicAndre1981 Hi MagicAndre1981, was ist in vLite mit Eingabezeichenfolge gemeint? Gehe ich zu den Fehlerdetails erscheinen einige Compiler Parameter $String... u.s.w. Da hört es bei mir leider auf. Best regards Thomas
