Unable to open /designer in new 7.9 install

Certified Lead Developer

I have installed appian 7.9, its a fresh installation. But whenever I click 'Appian designer' link it displays 'Error 404 - Page Not Found' message.
I got below error message from application-server when I hit the link,There is no cause by statement present in this error message stack trace.

Please refer attached screen shot.
Note: I haven't started search server as m/c is already running out of memory
