Current release
AERL Link 1.0.4.17
Published September 2026
Recommended for all new installs. Each time AERL Link starts it checks for a newer release and offers to install it.
Previous release
AERL Link 1.0.4.6
Published July 2023
The last release published from the previous update address. Installs of 1.0.4.6 and earlier check that address for updates, so they never offer 1.0.4.17 or later.
To move to the current release, install 1.0.4.17 from this page.
USB driver
Windows normally installs the USB driver automatically the first time a device is plugged in. If AERL Link does not detect your device, run the driver installer, then reconnect the USB cable. The same driver works with every AERL Link release.
Installing
- setup.exe installs the same release and adds Microsoft .NET Framework 4.7.2 if the PC does not already have it. Use it if the Install link does not start.
