Hi! I have to admit a did not read through the whole thread, but the forum search couldn't help me so I thought asking wouldn't hurt :-) Since RT Seven Lite is explicitly intended for Win7 it is safe to actually use all it's options, isn't it? I ask because I tried to produce I custom build but directly after entering the setup I get the error "The product key entered does not match any of the Windows images available for installation." and it stays even when I delete the Autounattended.xml which contains the key. I experience similar problems before while I tried to use vLite without knowing about it's shortcomings with Win7 (). Therefore my question. Using RT Seven Lite Beta 1.0.7 64-bit on a 64-bit Win7 installation. I can provide the exact options I chose, but it's quite a lot of them (driver integration, component removal, tweaks, unattended option). Any help/hint to solve the issue are appreciated :-) Edit: I just noticed an unanswered error report in the "RT Se7en Lite" forum (http://www.rt7lite.com/rt-se7en-lite-forum/6-unattented-installation-support/448-lost-unattended-setting.html). Just wanted to add that this is also valid for me -- unattended settings lost + scrambled license key. At first I thought this was my problem, that I mistyped the serial. But a new run with a definitely correct serial brought the same error message as does deleting the Autounattended.xml.
