Here’s what I suggest you to do:
- Go to Programs and Features, look for evolve. Right mouse click and chose ‘uninstall’. Follow the instructions.
- Once finished, open Steam. Go to your Game Library, scrol to Evolve and right mouse click on the title to open a drop down menu.
- Chose Properties - Betas. Under ‘Select the Beta you would like to opt into’ click on the arrow to change from ‘NONE - opt out of all beta programs’ to ‘legacyevolve - The Original Evolve Product’. Then close the window.
- Now Steam should automatically begin installation and if not, simply click on the Install button under the game from the Steam Library page.
If you do not have this option, then maybe the code you redeemed was already used by a different account OR unlocked something else (pre-order and DLC codes do NOT unlock the base game).
One way to verify is by click on your Steam account name in the upper right corner. Then chose Account Details and click on ‘View licences and product key activations’.
In there you will find a list of all the games you redeemed on your account via a code, or bought. For example looking at mine it says: Evolve - Retail Pre-Order. This lets me know I bought the base pre-order game.
