The “path” in windows is a setting that tells the system how to find things- so, when you type “java” on the command line, and it says “not found”, it means that the location where java is installed isn’t on the windows “path”.
We also would like things to go smoothly, but sometimes various things work against us. When our installer detects that java is missing, it installs it and puts it on the path. In your case, though, java is already installed- it just wasn’t put on the path (we’ve seen this in various cases). Ignition depends on java being on the path by default, because we can’t know where every user will have Java installed.
Not to fear, though, as it’s easy enough to change:
- First, track down where java is installed. It should be somewhere like [tt]C:\Program Files\Java\jre[version number][/tt]
Since you’re using 64-bit, make sure it’s under “Program Files” and not “Program Files (x86)”.
- Under that folder you’ll have a “bin” folder. This is where all the java programs are. Copy the full path to that folder.
- Now locate the Ignition install directory. It will be in “Program Files\Inductive Automation\Ignition”. In might be in the “Program Files (x86)” folder, but don’t worry about that.
- In the Ignition install directory, there is a file called “Ignition.conf”. Open that with notepad.
- Towards the top you’ll see: [tt]wrapper.command.java=java[/tt]
Change it to have the full path in there: [tt]wrapper.command.java=C:\Program Files\Java\jre[version]\bin\java[/tt]
Now go to Services under Administration tools (Start>Control Panel>Administration Tools>Services). Find Ignition and start it. You should now be up and running. Once the service starts you can open a web browser and point it to [tt]http://localhost:8088[/tt]
Hope this helps, let me know if anything is not clear.
