So success. What was it I did though?
Last night I once more booted my computer into safe mode with networking and set about trying to resolve the INST-3-1920 error using the app or the "insufficient privileges to run EABackgroundService" using the msi install method. My main focus was on resolving EABackground services using Powershell which ultimately led me to copy some files and reboot the computer as normal and try the install. And the EA App installed and is now running. I am 99% certain I hadn't "fixed" either the INST-3-1920 or the EABackgroundServices not running by doing some complicated stuff. So what was it?
There are various threads and answers about INST-3-1920 and the EA App that talk about deleting and all reinstalling Visual C++ files. Yes I repaired or reinstall those last night but I did that the night before as well and could not get the app to work. I also read threads on 1920 issues not related to the EA App.
What interested me most though was the difference between a clean boot environment - which I had tried with no success - and booting in safe mode. This led me to a discussion on some software providers saying to run sfc and dism in a clean boot environment and some providers saying to run sfc and dism in safe mode.
And as a result one of the things I did differently last night to run both sfc and dism in safe mode with networking.
Would the app have installed if I had run just sfc .... maybe. Would the app have installed if I had run just sfc in a clean boot environment .... maybe. Same questions for dism.
If clonselnsohn you try this and it doesn't work for you let me know. In my attempts there was some other things I did but I hadn't done all that I needed to do if that was the solution.
I feel happy suggesting this solution.
Other threads on the EA App issues and errors seem to work for some but not for others; very random.
Running sfc and/or dism is also a suggested fix but in normal mode which didn't work for me.
So my suggestion: Run sfc and/or dism using a clean boot or safe mode.
I actually think its easier to boot into safe mode rather than going through the steps to get a clean boot environment but whilst you can run sfc in safe mode (which may work!) you need to be connected to th einternet to run the dism /online which means you need safe mode with networking and a cable to connect your computer to the internet with a cable. And these days some people may not have a cable.
On CCLeaner: I had no issue getting the EA App onto a computer on which CCleaner is run much more frequently than on the computer that had the issue. Which is not to say that it was not the cause of corrupted Windows image. It could have been another uninstalller or - who knows. CCleaner is widely used and has been around for decades so it would be hasty and maybe harsh to blame it.
