Download the Official Homecoming Launcher and you won't have that issue.
HC Launcher has three primary design goals: Speed, Security, and Compatibility.
Speed: The launcher is supposed to get you into the game, it shouldn’t take any longer than absolutely necessary to fulfill this function. Tequila and several other launchers are based on .NET, and as a result have noticeably slow startup times on some systems. HC Launcher is designed not only for fast startup and faster patching, but also to avoid long and unnecessary file verification, or delays due to Internet latency.
Security: This has been a frequent criticism of Tequila and its use of unauthenticated manifest files. By putting in a manifest file, you are in effect trusting the author of that manifest with complete access to the user account you’re running it under, since it can download and run arbitrary code. It also lacks protection against man-in-the-middle attacks, making it impossible to know if a malicious third party has hijacked the manifest. HC Launcher addresses all of those issues by using strong cryptography to verify the integrity of itself and everything it downloads. More details can be found in the technical deep dive post.
Compatibility: HC Launcher is written in C and uses many of the same libraries as the game itself. As a result, it should run in any environment that is capable of running the game, such as wine on Linux/Mac, without any additional work.
Important note: HC Launcher uses a different file layout for the client install, reorganizing it to make it easier to manage. As a result, it cannot coexist with Tequila and must be installed to a different location. By default it attempts to locate existing files to avoid having to redownload them, as well as migrate user data. More information about the new layout is available in the technical deep dive post.
