I found a solution that worked for me and is easy to do.
Start your PC or restart in safe mode with networking. To do this just hit your windows key + R at the same time and a run box will come up. Type in MSCONFIG(system Information).. click on the boot tab and make sure safe mode is checked as well as network. Click apply and it will ask you to restart.
Just find the Install_ESO file you have saved and install while in safe mode with networking. After you get the ESO launcher installed you can restart by going back to MSCONFIG and unchecking safe mode under the boot tab. It will ask you to restart again and now you should have the ESO Launcher installed so you can continue to download the game.
It worked for me Windows 10 64bit
