Warning: Only download and run software from sources you trust. Malicious archives can contain malware. If you’re unsure about the file or site (for example "www51scopecn"), do not proceed.

You’ve downloaded the file. It is named setup.rar . A .rar file is a compressed archive—think of it as a suitcase. It’s packed tight to save space and often requires a specific tool to open it.

Following this guide should give you a clean, functional installation of the suite from www.51scope.cn. Keep the original download archive and your config backup in a safe place—future upgrades or migrations will be far easier with those at hand. If you run into an issue not covered here, consult the official docs/InstallGuide.pdf bundled with the download or reach out to the 51Scope support forum.
