Thanks for your suggestion Christian. I followed your adive but looks like my CA is not getting called at all. I checked the verbose log and there is no entry of my CA.
Following is how I have defined and sequenced my custom action. SOLUTIONEXISTS = notexists NOT Installed NOT Installed I have not sequenced any custom action in UIExecute Sequence. Is the CA sequenced properly here, as I want to check and display message before any installation process begins. Please advice.
