Hi Tried out the new 7C version 0.5 beta, and used the a "Windows 7 x64 Enterprise SP1" as the source. I didn't include anything (drivers or hotfixes), but made some random adjustments (unattended. This gave me a dialogbox with the following text: "Windows could not complete the installation, To install Windows on this computer, restart the installation." The "computer" was a VMWare workstation 7.1.3. If I tried the same source with no manipulation all functioned well. No error was reported though the 7customizer processing I have included the log files I found on the 7Customizer folders. Regards B115242 log.zip
