# Launch WPF application using Process.Start

I am attempting to [launch](https://www.mindstick.com/news/2241/what-does-the-launch-of-google-cloud-s-own-node-hosting-service-mean-for-web3-developers) a [wpf](https://www.mindstick.com/forum/304/wpf) [application](https://www.mindstick.com/articles/12824/calculator-application-in-android) using [Process](https://yourviews.mindstick.com/story/1525/7-important-factors-that-may-affect-the-learning-process).Start.

```
var programPath = @"C:\Users\user\Documents\Program
Directory\program.exe";if(!File.Exists(programPath)){    
MessageBox.Show("The program.exe file does not exist! Cannot
launch.");     return;}Process.Start(programPath);
```

My WPF process flashes in the [task](https://www.mindstick.com/forum/161761/what-is-the-difference-between-task-and-thread) [manager](https://www.mindstick.com/articles/13000/perks-of-implementing-a-quotation-manager) briefly before immediately closing.

Hi John,

```
Process proc = new Process();proc.StartInfo.FileName = programPath;proc.StartInfo.WorkingDirectory =
Path.GetDirectoryName(programPath);proc.Start();
```

The trick was to set the working directory to the path of the WPF application, rather than the working directory of the launching application.
