Can't reinstall after uninstalling to fix
Wasn't able to verify files so I tried uninstalling and now it won't install from the client side, saying: Error Something went wrong. Please try again.
Having this same issue. Unable to update launcher, uninstalled and reinstalled everything fresh. Redownloaded completely new game and launcher, got to a point where I could no longer update anything.
Circumvent the Launcher and login to the game via the .exe, it will force you to update, then say the update couldn't be applied. After that, restart the launcher, it will apply the update to the launcher, and you're in.
Select the Start button and click Settings (the cog icon).
Search for Recovery in Windows Settings.
Select Recovery > Open System Restore > Next.
Select a restore point that was made before you uninstalled the program. Then, click Next.
