Installer and device architecture
AMD64 and x64 usually mean the same 64-bit x86 architecture, regardless of processor brand. ARM64 uses a different instruction set; don’t treat the two as interchangeable just because both are 64-bit. Check your system architecture, then read the file details beside the download button.
If the installer says your system isn’t supported, check the OS version and file architecture first. If the app opens but the core won’t run, check core logs and runtime dependencies. This page doesn’t give one minimum OS version for every client; refer to the selected app’s release notes.
Updates and configuration migration
Back up your local configuration, subscription source, and overrides before updating. Numbers in installer filenames and app release information are separate details; don’t use a single number on this page to judge which platform builds are newer. The release notes and in-app version information are better sources for what changed.
When switching clients, quit the old process first, then import your subscription and enable the configuration. Check the system proxy, proxy group, DNS, and listening port before testing access. If only one app can’t connect, check whether it uses the system proxy instead of deleting all your configuration. See the Getting Started guide for detailed steps.
