How to Run AirTOP Versions Requiring Java 8 After Upgrading to Java 17 (Legacy)

AirTOP (v4.0.0 to 5.1.3) require Java 17 (64-bit), while earlier versions require Java 8 (64-bit). To install/run both versions in parallel, you must install both Java 8 and Java 17 on the same machine.
 

Steps to Launch AirTOP Versions Requiring Java 8

To ensure older AirTOP versions use Java 8, follow these steps:

1. Open the startup script

  • Navigate to your AirTOP installation folder.
  • Open the appropriate .bat file using a text editor:
    • Standard version: AirTOP_64bits_3gb.bat
    • USL/TSL version: AirTOP.bat (located in the Program Files directory)

2. Update the Java path

  • Locate the following line in the file: PATH %PATH%;%JAVA_HOME%\bin
  • Replace it with: set PATH=C:\Program Files\Java\jre1.8.0_361\bin;%PATH%
  • Update the path above to match your local Java 8 installation directory.
    - Example: C:\Program Files\Java\jre1.8.0_361\bin
  • Save the modified .bat file. Launch AirTOP using this script to ensure it runs with Java 8.

Notes

  • No changes are required for AirTOP compatible with Java 17; it will use Java 17 by default.
  • Ensure both Java versions remain installed to avoid compatibility issues.
