Error "Downloaded file checksum does not match" in launcher

For some reason, the downloaded file is corrupt. Such a problem can be caused by several reasons, for example:
- Intervention of third-party software in the download process (antiviruses, firewalls both on the end device and on network equipment)
- Failed network card driver
- Active PC virus infection
- Problems with the file system on drive C (the temporary directory with the downloaded file is located there)

Try to restart the installation of the game.
If the error repeats, you have to: check all your PC drives with the system utility chkdsk; check PC with anti-virus program; Install all updates to your OS; Install the latest drivers. Also, try to temporarily disable the antivirus/firewall and add a launcher to the white list.
