I've made myself a unattended installation but during the critical updates installation i received a screen for the MDAC security patch where i have to click "OK" and then i receive another pop up saying "You will have to restart your machine" where i have to click "OK" then i receive another pop up "Do you want to restart your machine now" where i can click "yes" or "no" i'm using this line for the update in my bat file: start /wait %systemdrive\install\Hotfixes\Q823718_MDAC_SecurityPatch.exe /Q:A /R:N Anyway ideas? Also can i just confirmed that in order i should install applications first and then critical updates. My reasoning for this is some critical updates could be related to wmp9/dx9b or msn6 so installing them before the applications wouldn't make sense, right? Anyway cheers in advance.
