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
