Hello sudarshan55,

Welcome to FORUM !!

You will be able to install and run WIN 7 64BIT OS successfully as the unit is already supporting WIN 8 64 BIT OS.

The specs your unit shows, shipped with
4 GB 1600 MHz DDR3 and Windows 8 (64-bit)

Now your PC would work fine, but I would personallly recommed you to add another 4gb of RAM and make it 8GB in total for better performance. It has 2 user accessible Memory Slots. 

NOTE : Your PC can support upto 16GB of RAM
