Solution 2

The path you're trying to execute has to be enclosed in quotes in your command line.

The command line you appear to be trying to execute is:

cmd /c C:\PROGRA~1\My App 4\Compare\app.exe

What you need to be executing is:

cmd /c "C:\Program Files\May App 4\Compare\app.exe"

Any path that has spaces in it must be enclosed in quotes.
So, the quick'n'dirty method of setting your Path would be

string Path = "\"C:\\Program Files\\My App 4\\Compare\app.exe\"";

For Progarm Files we using PROGRA~1. Like this way any solution to implement "My App 4"?

Dave Kreskowiak 26-Oct-17 8:16am

Yes, I already told you how. If there is a space anywhere in the path, the path MUST be enclosed in quotes.

For Progarm Files we using PROGRA~1
Why? There's no point to it today.

Solution 1

You would need to put Path in double-quotes because it's used as an argument, not as the FileName here. Same thing as when you would type it into a command console manually.

Are you sure you actually don't want to execute your app directly, without the detour via cmd.exe? Like this:

C#

Process.Start(@"C:\PROGRA~1\My App 4\Compare\app.exe");

Thanks for your solution. I want to specify the path to a string variable as mentioned in the peace of code

Process.Start(@"C:\PROGRA~1\My App 4\Compare\app.exe"); only issue am facing is "My App 4" this folder names having spaces. Due to this space not able to run app.exe. for Progarm Files we using PROGRA~1. Like this way any solution to implement "My App 4"

Process.Start(@"C:\PROGRA~1\My App 4\Compare\app.exe"); will work regardless of spaces. Spaces are only a problem in your code because you use the path as an argument. Enclose it in double quotes, as I said and as Dave showed below.
