[wix-users] Custom Action firing

[Habib Salim]

Good Morning.

 

I have a custom action in my installer that prompts the user to select an
image file - a logo that will be used by the application.

The path to the image file is then stored in the application.config file.

(relavant code pasted below)

 

This works when I run the installer but it also runs on uninstall
(although it does nothing)

It also runs whenever a new user open the application for the first time.

 

How do I ensure that this opens only on the first install?

 

Regards

Habib

your reports" 

                

            };

            if (fileDialog.ShowDialog() == WinForms.DialogResult.OK)

            {

                session["LOGO_PATH"] = fileDialog.FileName;

            }
