Thank you for the feedback. The reason that we stay with JRE 1.4.2 is because there were some reported display issue in the subsequent JRE that some users fedback to us (but we could not replicate) between JRE 1.4 and JRE 1.7. When our users went back to JRE 1.4.2 the issue went away.
However, the newest JRE does have some nice features and Java developers may have fixed those bugs exist in the previous versions so some time in future we will move to use the new Java.
Meanwhile, if your current JRE works well for you, you can try to download the following alternative launchers.
http://www.tri-plc.com/download/TCurrJRELlaunchers.zipAfter you have unzipped the files, rename them as TL6Launcher.exe and TL7Launcher.exe and replace the existing files of the same name in the TRiLOGI\TL6 and TRiLOGI\TL7 folder. These two launchers will invoke the current JRE on your PC to run the .jar files. (You may want to keep the original launchers somewhere else in case the new launchers or new JRE don't work out too well).
Since these two .exe files are registered with Windows, double clicking on a file with .PC6 and .PC7 extension will invoke these launchers to open the data file using the correct i-TRiLOGI version.
