Can't Install Warcraft III: Reforged

I own Warcraft III: The Frozen Throne, Warcraft III: Reign of Chaos and they are both in my battle net account. But on the desktop client (using this account) I musst buy Warcraft III: Reforged. So how do I get access to my games?

You must own either Warcraft III: Reforged or a classic Reign of Chaos CD key. If you own a classic Reign of Chaos CD key, you must redeem your CD key on your Battle.net account before you log in to the Battle.net app.

If you are only seeing a “Buy” button then it could be that you are logged into the launcher on a different account from the one you have the CD keys claimed to.

No it’s definitely the same account on the desktop client and the browser.

You don’t need to buy it then, but simply install the WC3:Reforged Client, and when you go to install it you will be prompted to validate with your CD keys from the account.

You should clear the Battle.net App Cache as this could be causing the issue.
