One of the most frustrating errors in Final Fantasy XIV can be the dreaded “unable to perform version check” error which occurs just after you load the launcher for the game and click Play. Luckily, there are a few fixes that solve this issue.
The first is to reload the launcher. In the vast majority of cases this issue occurs during the downloading of new data. Reloading the launcher solves this.

If this doesn’t solve the issue, the next step is to verify and repair your installation. To do this in Steam, right click the game in your Library and navigate to Properties. Select Local Files, and then Verify integrity of game files. Once this process is complete, reload your game and the error should be gone.
The next step, or if you’re not a Steam user is within the launcher itself. Click on the cog symbol in the top right corner of the launcher, which will have hover-over text reading Config. In the bottom, you’ll see two options, Reset System Settings, and Restore Game Data. First attempt to Reset System Settings and then test to see if the error still happens. If it does, attempt to Restore Game Data.
If the error still persists, then it’s time to fully reinstall the game. Before you do so, you should backup your User files, which will contain your character’s User Interface and Options details. Reinstallation will not affect your in-game data, but various preferences and options will be lost. This should in most cases solve the version check error.
