Now I'm back. Test31 works without problems, only two small things, not really important: 1) Only 1 of three windows-gadget have been integrated; the missing kan be loaded after install. 2) 1 Tweak, "Larger Taskbar Previews", is not present in the VM; I'll install an older ISO, to see how was in the past. MfG, Thiersee Edit: 1) In Test24B two of three gadget have been integrated, the third not; the error was the same as from @RicaNeaga (next Post); I can't say, if the same error has been generated in Test31, I was not present (eating!). 2) Tweak is in the registry, may be it is not visible within a VM.
