Ubuntu Software Center Not Working Properly

[vishal1875]

Hi I Am Vishal,
Actually I Stuck in a Problem which is related to The Ubuntu Software Center Which is not Installing any software which i select from the Software center,
When i click over Instal Button it shows "Installing" for just 1 sec and then its gone back to normal means not installing, i have tried many commands on Terminal like
Purged the Software Center and re-installed it again through some commands
Even Synaptic Package Manager is not working from Start Main Menu.

But When i use commands like following in Terminal they both applications works fine also installs that application which i choose to install:
gksu software-center
gksu synaptic

I don't know why these applications not working properly as normal
they just only works with commands in terminal not from Start Menu

I am Newbie Ubuntu User. Plz Help Me

My system Conf:
Xubuntu XFCE 12.04
Genuine Intel Pentium 4 Processor
1GB RAM
80GB HDD
256MB ATI Graphics Card

Rest all works fine, I love that OS, But only that problems me alot because of software installation

Thanks in Advance....:p
