Capella install Error

I am new in Capella and the installation fails when I launch eclipse.exe. The Eclipse launcher points out to a Workspace at: C:\A_user\Personal\Apps_and_Utilities\MBSE\capella\eclipse\w orkspace.
After clicking ok, an error message appears indicating to look at the log file.
The log file reads:

Any suggestions?
Thank you

I don’t believe Capella has been tested with version 10 of Java. Capella 1.2.x is validated on Java 8. I don’t know whether that makes a difference…
