           File.WriteAllBytes(@"c:\temp\canva.xlsx", myfile);
           MessageBox.Show("Canva Loaded Successfully", "Information");
           Process pross = new Process();
           pross.StartInfo.FileName = @"c:\temp\canva.xlsx";
           pross.Start();

Seriously? Look at your code and the filepath you are writing the bytes to.

All you have to do is supply a different filepath. That's it!

But, you would have known this had YOU written the code instead of copy'n'paste coding.

I don't need a static path like that @"c:\temp\canva.xlsx", myfile i want the ability to choose the path using save dialog

An SaveFileDialog will give you that. All it does is return a string that represents a filepath. It's really easy to use, as shown in the other answer.

.. but computers are dumb - that's what you told it to do here

File.WriteAllBytes(@"c:\temp\canva.xlsx", myfile);

you probably need something like

SaveFileDialog savefile = new SaveFileDialog(); 
// set a default file name
savefile.FileName = "canva.xlsx";
// set filters - this can be done in properties as well
savefile.Filter = "Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*";
savefile.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
if (savefile.ShowDialog() == DialogResult.OK)
{
    File.WriteAllBytes(savefile, myfile);
}

This

Quote:
savefile.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);

can be set to anywhere appropriate for your application

Does that solve your issue ?
