What do I do if I receive the error "Invalid Drive" when installing the Epic Games Launcher?

Invalid Drive error in the Epic Games launcher

Before a game or program is installed, you're prompted to select an installation directory. This directory is assigned a hard drive letter. By default, this is your C: drive:

The Invalid Drive error appears for one of these reasons:

  • The hard disk your operating system is installed on has changed (drive C: is most common) or the drive letter of the DVD-ROM or CD-ROM has changed since a prior install of a program. 
  • There’s an incorrect value in the Data filed of a registry key.
