A couple of days ago I installed Unity and that in turn installed "Visual Studio 2017", the rest of the day every time I launched ESO it gave a prompt "Do you want to allow X to make changes to your computer" I can't remember what X was now.
It did launch and play though, but today every time I click "play" in Steam it changed to the blue "Stop" button and then after 10 seconds returns to "Play" having not started anything.
I can get the launcher to run if I go into the folder and run the "Bethesda.net_launcher" it ran an update and launched but Steam does not know it is running and ESO wont log in because it wasn't launched from steam, I Can use my account log in to get online but one time I got a notice about "This was not launched from steam" or words to that effect and there was no log in "Name and Password" box, just the (eso log in screen) Play button.
So far I have verified the files, OK
I uninstalled Visual Studio 2017.
uninstalled, rebooted, reinstalled eso, I get the old school brown installer then the black screen saying "Hero" then it goes away and steam returns to "Play?"
Tried to run vcredist_x64, x86 and the 2015 variants but the computer says it can't because newer ones exist, so I uninstalled them and reinstalled them from the (Zenimax online>Launcher) folder, this did nothing, Bethesda.net_laucher had a shield symbol on it so I ran that and it has admin rights, it also added more files in the folder after it ran.
So currently Steam still not launching and I can log in using my old school password, can anyone help me get steam to actually bootstrap/ do it's job?
