The 'Application Initialization Error' is only returned from the online (web, shim) installer (the one in your screenshot). According to the online installer team, this happens when the APP file is extracting out of the mounted DMG. Are you mounting the DMG and then dragging the APP file out of the mounted DMG onto the Desktop, or some other location, then launchign the APP from that location? Originally, I had mounted the DMG and then opened the installation file from the mounted DMG. Should I be taking the installation file out of the mounted DMG and then opening it from my desktop? I just gave that a shot but it didn't seem to make any difference. I even tried extracting the installation file to the desktop and then unmounting the DMG and trying it that way too. All with the same results. I've never seen the offline/standalone installer return the 'Application Initialization Error'. Please post a screenshot of the offline/standalone installer returning the error. Apologies, I had gotten confused about this. I have never used the offline/standalone installer mostly because every link I tried to direct me to it brought me to this screen about "flash player distribution" and when I clicked on the "individual customer" option it sent me right to the regular flash player. I had mistakenly thought it sent me to the standalone one, which was why I thought I had used it but I actually hadn't. This document refers to the Extended Support Release, which we did stop supporting some time back. It is NOT referring to the offline/standalone installers for the currently available release, which have always been posted at the bottom of the Installation problems | Flash Player | Mac page, in the 'Still having problems' section. Ah, my apologies. It seems I didn't understand the context of that post. As I have not before come across the page you linked, I will go ahead and read through it and let you know if it fixes the issue. Thank you for taking the time to go step-by-step through this process with me. It's much appreciated!
