Important changes to how games work on Windows 7

In May 2021, the launch of the game will become impossible without the support of the digital signature based on the SHA-2 hash algorithm. If your operating system does not have all the updates installed in the "Windows Update Center", you can enable the SHA-2 support manually or upgrade your Windows 7 to Windows 8 or a more recent version. To activate the SHA-2 support, follow the instructions.

5. Save your work and close all open programs to avoid losing your data and to speed up the installation. We also recommend ticking the "Automatically restart the computer" checkbox. The installation of Service Pack 1 will start only after you click the "Install" button.

In some cases, support for the SHA-1 digital signature hash algorithm may not be automatically updated to SHA-2.
