We were not able to get the keep files and settings thing unless the following is true: No ei.cfg --or-- ei.cfg set to a specific editionid (hence this whole thread) --and-- run setup.exe from the root of the RTM dvd, not the sources\ folder
I've tried changing the cversion.ini and changed lang and region too US and run setup.exe from root of dvd but still no joy do u have any other ideas??? I downloaded the preview .iso from Microsoft for united kingdom would that make any difference in upgrading too RTM???
I created an AIO x64/x86 Windows 7 iso, and AOI x64/x86 8.1 iso. both worked perfectly, but if I make a single install.wim of Win7 and 8.1, in initial setup, it ended up with this error: installation key error. what there is any ei.cfg or unattend.xml to solve this problem?
