This has, sadly, been going on for Months. I think it started last November.
Back then, when trying to Login via Origin, an annoying EA App pop up appeared instead, demanding that a new EA App be downloaded, after which Origin would be deleted.
Except the EA App failed to load, and fell over every single time.
Downloading the EA App direct did not work either.
After a ton of complaints, EA relented and re-enabled the Origin Login.
So, the Origin Login worked again fine for a month or so.
Then they forced the EA App upgrade, again, but without trying to fix the issues that caused Origin based users grief back in November 2022.
Many, myself included, found a way around that by modifying an XML File, which kept Origin working by stopping the EA App pop up.
Then they stopped that workaround, and forced the EA App yet again but, you've guessed it, without trying to fix the issues that caused Origin based users grief from November 2022 onwards!
Downloading the EA App and trying to install it that way, still doesn't work either.
In am now totally unable to launch C&C Red Alert Remastered.
There is no workaround that I am aware of, other than downloading an old version of Origin, which one can only obtain from non-official web sites, which in my long experience, is not worth the risk of downloading something extra.
To say I am unimpressed with EA, would be an understatement.
