Solution 3: Update Drivers

To play games seamlessly on your PC, you need to ensure that your drivers are up to date. If one or more of your device drivers are corrupted, missing or incompatible, it’s likely to cause a myriad of errors, such as the “FFXIV Launcher Error. Unable to complete version check” error.
