Question

I have a 3rd party software package. Its folder contains the .exe file to run and some other files required to run the application. When I open the application manually, it works fine, but when I try to open the same application through Process.Start(), I get the error “application has stopped working”.

The application needs the .NET 4.0 framework in order to execute, so I had to install it. The C# code I’m attempting to run it with is on .NET 3.5 and was created using Visual Studio 2008.

You could try the following:

    var path = @"C:\Temp\test.exe";
    FileInfo fi = new FileInfo(path);

    ProcessStartInfo info = new ProcessStartInfo(path);
    info.WorkingDirectory = fi.DirectoryName;

    Process process = new Process();
    process.StartInfo = info;

    process.Start();

If this does not work, try

Directory.SetCurrentDirectory(fi.DirectoryName);

directly before the process.Start();

Do not forget to reset the Current directory afterwards!
Save the CurrentDirectory before with

var currentDirectory = Directory.GetCurrentDirectory();
