Ok, started with brand new Windows XP SP2 OEM disk, setup Unattended section, works great. But... Integrating IE7 / hotfixes / WMP11 (even tried individual images with IE7, then with WMP11 integrated by themselves) and durring XP installation (at least on Micro$oft Virtual PC 2007, with a 16Gb virtual drive), installer copies files, reboots, gets to the full colour GUI install, before this fully loads, XPSP2 install returns an error "Not enough virtual memory" and goes into endless reboot loop. I've tried heaps of different things to sort this out (so there's a lotta "last session.ini"s to go thru, so far the only way I can get the ISO to work properly is to use only unattended section with no hotfixes. Also, even if I choose "merge" under the extra options, I'm still getting a "$OEM$" folder on the image. Anyone have any ideas? I'll post again soon after I test the next image, I'm expecting it to fail again, so will post a screen of the VM error and the last session for this ISO. nLite 1.4 Beta WMP11Slipstreamer 0.85
