[quote name='I cleaned out everything I wanted to with 1.3.5, then used 1.4 for the handful of new removal options, and it installed fine, so it looks like it's one of the old options messing up the 1.4 install. Can you be more specific please. which version u used to slipstream the hotfixes the 1.3.5 or 1.4? i have to used the 1.4 only for removal or 1.3.5? and the full process (tweaks, unnattendend, integration and options) , will be in hands of 1.35 or 1.4 thanks in advance
