Validation Error: while installing LC ES2.5 on w7 (Invalid Domain Name)

Hi,

I have installed LC ES2.5 on Windows7(32bit, 4gb Ram) machine. During Configuration (In Express Mode) I am stucked at Configure turnkey JBoss SSL step. I have filled the entries as below.

When I click JBoss SSL it throws an Validation Error stating that :

Invalid name for Common Name. The value is required to be Fully Qualified Domain Name.

I have tried many options but not able to get out of it.

I am new to LiveCycle, please help.

Thanks in advance.
