start up error occurs after launch v5.5

Just wanted to share for others to know how to resolve this issue.

I am trying to launch Soap UI OS, but I get this error. 

I even restarted my computer and I still get this error. 

I update my Java from 8u201 to 8u211. 


I looked deeper.  


I was launching SOAP UI via the Start Menu.  

This was invoking SOAP UI v5.4 instead. 


I saw that my Program Files had both v5.4 and v5.5 so I deleted v5.4
