60Driver Posted August 29, 2021 Posted August 29, 2021 I followed the instructions in the first post. The ISY Launcher app was created on my desktop. However, when the app is initiated a window pops up with "Cannot determine a valid Java Home". The header on the pop up window is: Java(TM) Web Start 11.171.2.11-fcs. I can start the ISY Finder by selecting from the Java control panel General->Temporary Internet Files->view and running the ISY Launcher. Then I can right click on the link in the ISY Finder to launch the administrative console. Clearly there should be an easier way. I repeated the installation process multiple times and each time the ISY Launcher started with the same message.

Did the installed java come from the offical Java website https://java.com/en/ or someplace else?

60Driver Posted September 3, 2021 Author Posted September 3, 2021 As I said in the first paragraph of my post. I get the error message when I try to run from the app icon.

60Driver Posted September 3, 2021 Author Posted September 3, 2021 Sorry. I did miss your question. It is Version 8 Update 301 (build 1.8.0_301-b09). Yes it came from the official Java website. Running on Windows 10 version 20H2
Techman Posted September 3, 2021 Posted September 3, 2021 It's possible that Java didn't get installed in the default folder. If that's the case, uninstall and reinstall it. The default location for Windows 10 is :C:\:ProgramData\Microsoft\Windows\Start Menu\Programs\Java

But I can launch the app from the Java cash viewer page.

60Driver Posted September 4, 2021 Author Posted September 4, 2021 20 hours ago, Techman said: Take a look at this How to set JAVA_HOME in Windows 10 | Java Tutorial Network I went through this. However, it starts out with setting path to JDK not JRE. I have a JRE directory. I subtended JRE for JDK and followed the procedure but had no effect. I cleared the cache and application and ran the start.exe again. The ISY Finder starts on it's own as part of install but once closed activating the desktop link results in the same message.
Techman Posted September 4, 2021 Posted September 4, 2021 (edited) This Is this the link you should use after you deleted your java files and applications. What version of the ISY firmware are you running? https://isy.universal-devices.com/start.jnlp Edited September 4, 2021 by Techman
60Driver Posted September 5, 2021 Author Posted September 5, 2021 The file "Start.jnlp" came from the link you posted. It downloaded to computer and I executed it. Firm where is 5.2.0

60Driver Posted September 5, 2021 Author Posted September 5, 2021 Sorry, poor spelling. Firmware is 5.2.0
Techman Posted September 5, 2021 Posted September 5, 2021 5 hours ago, 60Driver said: Sorry, poor spelling. Firmware is 5.2.0 If you're still having issues you may want to update your ISY to the latest firmware 5.3.4 and then clear your Java cache and applications and download the ISY finder again. The update from 5.2.0 to 5.3.4 is painless. 2
Geddy Posted September 6, 2021 Posted September 6, 2021 @60Driver, at this point I think it’s best if you open a ticket with support to get some one-on-one support. They may be able to help make sure you’re properly installing Java and the launcher app. Please submit a ticket via email to: support@universal-devices.com Good luck! 1
