There are several problems faced during retail online install. Many of them resolved by myself after a lot of trial and errors. Following seems beyond my capability :
1. Retail Async client install error: Retail Async server installed successfully and Retail Async client I am installing by clicking on "Configure Async Client" option. Even the test connection shows "Test successful" after putting Async server URL, Async Server and client user id, password and all. But after this page, when I move on to the end and click install the installer starts little progress and then sudenly stops showing "There is a problem with windows installer package...". But this error does not occur if I install Async Client without configuration. Now, that also does not work, if I try configuring it using Windows Power Shell. The commands for $Cred as described in installer guides does not work.
AX installer version: AX 2012 R3
