Get the user.config of one project in another project with same name of exe.

Question

Hi Guys,
How can we retrieve user.config file of one project in another project have same name of exe but different version number.

Description:
Create a simple windows application with title HappyDay
Store a variable in Settings named as Background and save a background color in it.
Place a button on it when button is clicked the background is changed by accessing Setting's background variable.

Create another project and do same step.

Build those projects.
Now rename the 2nd project exe with name same as 1st Project.

I want to get the configuration of 1st project on 2nd project execution.
Is this possible? If yes, then please detailed me how can it be achieved.
Thanks

Regards,
Itz.Irshad
