I performed the following steps below, but like the #1 post said I still have to use the native Elite Dangerous Launcher to play Horizons 2.0 ...(I can use the Steam client to play ED v1.5 if I want)...oh well:
Google link to screenshots I took during the process
Log into the Elite: Dangerous store.
- Go to your account dashboard.
- Click on ‘Partner Keys’
- Click Claim an ELITE DANGEROUS HORIZONS key.
- You should then have a ELITE DANGEROUS HORIZONS key appear in this screen.
Then log into Steam:
- There will be a update for Elite Dangerous (most Steam clients, have auto download enabled...so it should begin automatically), if you do not have auto download enabled for updates on Steam just navigate to Library -> Downloads ...then start the Elite Dangerous update/download
...this is a 8.1 Gigabyte update on Steam (took me 13 minutes to download)
- Then you redeem your ELITE_DANGEROUS_HORIZONS key from Frontier Store on Steam UI, by selecting Games -> Activate a Product On Steam
- Enter in you ELITE_DANGEROUS_HORIZONS key code "EXACTLY" how it appears on the Frontier Store in your account dashboard under -> Partner Keys -> ELITE_DANGEROUS_HORIZONS
- Now select play, in your Steam UI for Elite Dangerous
The Elite Dangerous Launcher should appear & you log into the ED launcher with your usual logon (email & password for the ED launcher).
- Now you should see a ED Launcher that is Orange & Black color with only the following play options:
ELITE DANGEROUS [32-BIT]
ELITE DANGEROUS [64-BIT]
SINGLE PLAYER COMBAT TRAINING
- So go ahead & log off the ED Launcher & then close it out.
Now navigate to where ever Steam installed the "EDLauncher.exe" & double-click it to open the ED Launcher.
Note: to find where Steam installs the Elite Dangerous game files do the following...
1 - log into Steam UI
2 - right-click on Elite: Dangerous & select "Properties"
3 - in the properties window that pop-up, select Local Files tab
4 - then click on "Browse Local Files..."
....this should take you to the correct directory /folder on your computer that contains the "EDLauncher.exe" file you want
Now once again, you will see a Orange & Black ED Launcher, go ahead & log into the ED launcher with your usual logon (email & password for the ED launcher).
After logging in you should see it flash & then change to a Blue & Black scheme ED Launcher with the following play options:
ELITE DANGEROUS: HORIZONS [64-BIT]
ELITE DANGEROUS [32-BIT]
ELITE DANGEROUS [64-BIT]
SINGLE PLAYER COMBAT TRAINING
...so I can play Elite Dangerous v1.5 32-BIT through Steam just fine, but to play Elite Dangerous: Horizons 2.0 I have to launch the native EDLauncher.exe as post#1 of this tread said.
Updated:
.....uh so I was dumb & didn't notice that Steam had separated Elite Dangerous & elite Dangerous: Horizons.
So went to the Elite Dangerous Store page on Steam, selected "Play"...as it was in my library from the key I had already entered into Steam ealier from Frontier Store.- Then waited 10 min for the download to complete in Steam
- After download completed, I selected play from Elite Dangerous: Horizons
- selected my Steam play mode for ED: Horizons
- logged into the ED launcher that popped-up
- ED Launcher sent a email to registered email with Frontier with a verification code to enter in
- retrieved Frontier code from email 7 entered it into ED Launcher
- then ED Launcher 64-BIT for Elite Dangerous: Horizons YEA!!!

...updated the above Google link with more screen shots of what I did
