ARCHITECTURE
Architecture determines whether a package can run
x64 is common on Windows and Linux desktop computers; arm64 is common on Apple M-series devices, newer Android phones, and some ARM Linux devices. Universal packages usually bundle multiple architectures and suit devices with unclear information.
No architecture is inherently better for client features; it simply needs to match the device. If installation reports incompatibility, recheck the processor architecture before changing subscription settings.
PACKAGE FORMAT
Extensions indicate different installation methods
The Windows page provides ZIP packages, macOS uses DMG, Android uses APK, and Linux provides deb or rpm according to the distribution. These formats differ because operating systems use different installation mechanisms.
Before downloading, verify the platform, architecture, and format together. Linux users should pay particular attention to the distribution’s package system; macOS users should check the chip field first.
UPDATE
Keep configuration details before updating
Before updating the client, record the subscription group names, current routing mode, system proxy status, and custom rules. After updating, confirm the subscription list is complete before restoring advanced settings one by one.
If the new version behaves unexpectedly after launch, do not change the subscription, routing, and proxy mode all at once. Test the basic connection with default settings, then use the logs to determine whether the issue is configuration or the system environment.
SUBSCRIPTION
Assess the client and subscription service separately
The client reads configuration, runs the core, and handles system traffic; the subscription link is maintained by its service provider. Installing the client does not create a subscription or fill in missing server parameters.
When a subscription update fails, first confirm that the link is complete, the system time is correct, and the subscription is still valid, then check the client logs. Visit the troubleshooting page for detailed next steps.
