If you encounter a JavaScript error while installing, updating, or opening the Reolink Client, this guide will help you troubleshoot and resolve it quickly and effectively.

Symptoms of Reolink JavaScript Error

When attempting to install the Reolink Client on your computer or laptop, you may receive the error message: "A JavaScript error occurred in the main process."

This usually happens because after the Client program is developed, it relies on certain runtime environments or system libraries to run on Windows or macOS. If the required environment is not properly installed or configured, the program may crash or display this error.

Here’s how to address it on Windows and Mac:

Fix JavaScript Error on Mac

  • Error: Dynamic Linking Error: dlopen

    mac javascript error

    Error 1: The macOS dlopen function cannot find the required library file.
    Solution: Upgrade your Mac system to macOS 14 or above.

    Error 2: App Translocation means the Client may have not been installed. Since the Client was downloaded from the internet, macOS treats it as unverified and runs it from a temporary location, which may cause the Client to fail to load its library files.

    Solution: Do not double-click the Reolink Client to open it. Instead, right-click → Open, or move the client to the Applications folder and run it from there.open client on application

    Alternatively, macOS needs to allow apps downloaded from the internet. To do this:

    1. Open System Settings → Privacy & Security

    2. Scroll to the Security section and click Open Anyway next to the app if needed.
