Recently. Oracle has released Java update version 8u31. After updating the Java installation, I noticed that the ISY administrative console shortcut stopped working complaining that it could not find the program. Windows will offer to delete the shortcut. DO NOT delete the shortcut. Here is how to make the shortcut work.
After checking the shortcut properties, I noticed that the shortcut was still pointing to the old Java install 8u25. Here is how to fix it;
I have the shortcut pinned to Taskbar. Open the ISY Administrative Console properties by right clicking on the shortcut, right click on "ISY Administrative Console", select "Properties" from context menu.
In Target box modify the program location as:
Old value:
"C:\Program Files\Java\jre1.8.0_25\bin\javaws.exe" (your version can be different)
New value:
"C:\Program Files\Java\jre1.8.0_31\bin\javaws.exe"
Click Apply and Ok.
Now the admin console will work. The same steps apply to ISY Dashboard also.
If your shortcut is on the Start Menu->All Programs->ISY994 Series->ISY994 Administrative Console, you need to right click on "ISY994 Administrative Console". Windows will immediately offer to delete the shortcut. Select No and then Windows context menu will pop-up. Select Properties and modify Target as per instructions above.
Considering security issues with Java, it is always a good idea to keep Java updated.
