You need to associate an application which will by default open .png files. This can be done from Control Panel. For example in Windows 7 go to: Programs -> Default Programs -> Make a file type always open in a specific program then scroll down to and select the .png extension click on Change and select a default application such as Windows Photo Viewer. Alternatively if you don't want to make a permanent setting then use the Process class to run the .exe you want to use and pass it the path to the .png file as an argument.

wonderful thanks. Why is it that the Default program with Windows Photo Viewer will work while Default program using Paint will not work?
