Search and run a file?

Hi, I have a question and any help is appreciated. I'm making a trainer/launcher for a game. The makes a backup, then modifies the .exe file of the game. Now, a problem came up that has stumped me. Right now the program has a default path, such as "C:\games\game.exe" that it executes. But not everyone has it installed in the same place. So my question is if there is a way to have the trainer search for game.exe, no matter where installed, and execute it? I know searching the whole C:\ drive is impractical, so maybe just a certain directory, like C:\games. If that is not possible, and help on getting a prompt to where the user can browse and select the directory where his game is installed.

Sorry if I sound like a n00b (I can't help it XD), and any help is appreciated.

Why not just have them keep it in the folder and then start it from the folder. That way it does the application start up path and can open from anywhere as long as it is in the folder.

You can easily give user option to select the game executable, with OpenFileDialog
and to run executable:

Code:

If Me.OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
        Process.Start(TextBox2.Text)
        End If
        OpenFileDialog2.CheckFileExists = True
        OpenFileDialog2.CheckPathExists = True
