Hi everyone, I'm new so can't post links - I've included links but you'll have to manually open them sorry. I followed through this guide to make a "Multi-brand" DVD to use with an Acer Aspire One D257 which came with Win 7 Starter pre-loaded, with the intention of putting on Windows Ultimate or Home Premium: forums.mydigitallife.net/threads/15733-Windows-7-DVD-(Multi-Brand-Multi-Edition)-Activation However when I install it onto the Acer, it asks for a Product Key. I referred to this thread: forums.mydigitallife.net/threads/10370-Windows-7-OEM-SLP-Key-Collection and entered the "Acer" product key for Windows Ultimate, but it was not accepted when it tried to activate online. When I looked at the OEM Sources thread: forums.mydigitallife.net/threads/12785-7-Oem-Sources-Folder-Project I noted that the Acer only had a file for Home Premium, so I reinstalled choosing Home Premium instead of Ultimate. However that also lead to the same problem and it wouldn't accept the Home Premium Product Key from the above page of SLP Key Collections! I went back to try and confirm that I have SLIC 2.1 - these are the screen dumps: Image link: iforce.co.nz/i/iyskgqtt.nxd.jpg Image link: iforce.co.nz/i/nm11thgt.41o.jpg It seems that I do have SLIC 2.1? What's going wrong? I previoius did the same thing on an HP and it pre-activated and never even asked for a Product Key to be entered?? Any help much appreciated thanks!
