Your users cannot modify a file located in Program Files.

If you have a configuration file you want to modify, you need to store it in the user's own ApplicationData folder, e.g.:

C:\Users\Bill\AppData\Local\SoftCo Software Inc\SuperApp\appconfig.xml

If you want standard users to be able to modify this config file, then your installation program is supposed to grant Everyone Full Control to the file. Your installation program is known to be running as an administrator, so it will have permissions to change permissions.

But you should not do that; this allows one user to alter program settings that will affect another user. These settings should be per-user (and stored in %AppData%, which the user already will have access to).

It is because of Windows UAC. You can fix the issue either

1. using Run As Administrator option, from right click menu in the application.
2. Modify the AppManifest file.
3. Change the file location user writable locations.
