Show your code.

Probably you think that starting one application from another one is a kind of "integration", but this is not. And a decent application's behavior does not depend on the parent process; having such issue means that your child application is not "working fine", you only have a false impression. I don't understand what kind of help could you expect with such "question". There is nothing to discuss here.

This is almost certainly due to the "working directory" for your WPF application.

When you launch the application from Windows, the working directory will be set to the WPF application's directory. When you launch it from your other application, it will be set to whatever you've specified in the ProcessStartInfo structure, and will default to the calling application's directory.

If your WPF application is trying to load files using a relative path, it will be relative to the working directory. When the working directory is set to the other application's directory, it won't be able to find the files.

Make sure you explicitly specify the working directory when you launch the application:
C#
Process.Start(new ProcessStartInfo(@"C:\Path\To\Your\WPF\Application\file.exe")
{
    WorkingDirectory = @"C:\Path\To\Your\WPF\Application\"
});

Hard coded path?

What?
Finally i found answer.....

Right-click on your image file and choose Properties.
Change the Build Action to Content.
Change the Copy to Output Directory to Copy if newer.

Use ". " Before path
Use "pack://siteoforigin"

="pack://siteoforigin:,,,./supportedfiles/resources/images/ribbonimages/New.png"
