Lyo Designer Will Not Launch

[andylapping]

Downloaded Lyo Designer and unzipped it - launched it and got the attached log
1641545178344.log

Installing it into an existing Eclipse using http://download.eclipse.org/lyo/p2/stable/ worked though.

Hi!

I assume you downloaded from https://download.eclipse.org/lyo/product/binaries/stable/ as instructed from https://oslc.github.io/developing-oslc-applications/eclipse_lyo/install-lyo-designer.html

Could you share a bit more about the environment you are running from? (windows/mac, etc.)

Could you also test with the latest version from https://download.eclipse.org/lyo/product/binaries/edge ? Will that be any better?

Sorry if this wasnt clear - I downloaded directly from the first link on this web page: https://oslc.github.io/developing-oslc-applications/eclipse_lyo/install-lyo-designer.html
That took me here: https://download.eclipse.org/lyo/product/binaries/stable/
I'm running Windows 2012 Server so I clicked: lyo-designer-win32.win32.x86_64.zip

Unzipped and ran the lyo designer exe

Tried the bleeding edge - looks like the same error

ok found the problem - multiple java installs. Running lyodesigner from a command line with -vm and a path to Java 11 - it launches

Goot to hear. Will keep this issue open.
I will update instructions to clarify that Java 11 is needed.
