I am attempting to look at an old FPMI project. I created an VM and installed FPMI, FSQL, & MYSQL from the original project Unified Installer that I have archived.

The installation went well. I made sure that I had Java Version 6 installed.

I had a problem with the starting of FPMI, and with the help of Tech support (thanks Paul) we figured out it was an IE compatability thing. I am now using Chrome and I can get to and see the Gateway now.  
I can start the application and navigate through the screens OK, so I don’ believe it is a java thing.

HOWEVER, the problem I hahe is I cannot start the designer. I get an error. I am posting the error below.
