Very recommended threads on ED forums for Steam users:

STEAM Discussion board about DCS World

What are the differences between the Standalone DCS World and the Steam version?

Steam Version:
- Auto-Update without launching the game (as long as steam is open)
- Faster Download/Update Speed
- Steam In-Game Overlay
- Steam Friend List Notifications
- Quick Repair
- DLCs not present on Steam are unsupported

Standalone DCS World:
- Get all the modules as soon as they are released
- Does not require any extra program to be launched
- Has every single modules available

If you are fine with waiting for most product to be available on Steam and like most of the Steam feature, the Steam version might be for you.
If you own unsupported products such as Upgrades / FC3 or do not care about the Steam functionalities, Standalone DCS World might be for you.

Another way to view your cd-key is by simply clicking the "CD-Key" link on the right side menu displayed after clicking DCS World within your library.

2. If you received a serial number for the module you have to bind it to account here: License serial number check and after that you will be able to install your product via in-game Module Manager.

3. If you unable to use License serial number check page, you need to activate your module in any DCS World version (Steam or from our DCS site) and then Log On under your account to DCS game and all the Star-Force keys from the registry will be automatically bound to account.

Download and installation FAQ

Are patches/updates for the Steam version of DCS released at the same time as the standalone? Is this a source of potential issues if both are installed and used between updates?

DCS World Updates are pushed through ED servers for the standalone and Steam Servers for the Steam platform thus resulting in a delay when using Steam (since Steam has to first receive and handle the new update). The good news is that the updates will be much quicker to download from your Steam platform. The negative side is that you might have to wait before being able to play with your friends using the standalone version on the latest revision.

Can I have both the standalone and Steam versions of DCS installed? Do they share settings? Are there any negative side-effects?

You can have both installations on your PC at the same time. There won't be any negative effects due to both installations keeping all their updates / configurations within their own folders.

My Steam DCS World does not show any key!

It can sometimes happen that the steam store run out of keys for the games sold on their platforms. Wait until the developers give them a fresh batch of keys and you will be able to get your key afterwards.

Please note from 12th May 2017 DCS: M-2000C and all future DCS World DLC releases on Steam, will now use Steam Keys instead of Starforce keys, therefore they not shown in Steam Library

I already purchased a module through Steam, but now it’s available for sale. What can I do?

The timing of your purchase is not within our control. Nevertheless you can try contacting Steam and find out if they can do something for you (perhaps in cases where you may have made your purchase within just minutes of a sale opening).
