Question

I’m trying to write a blank text file which is included within my installer but i’m getting the following error;

System.UnauthorizedAccessException: Access to the path 'C:\Program Files (x86)\Hex Technologies\wamplocation.txt' is denied.

It seems to be the permissions of the file once it’s installed through my installer, but how can I set the file to be fully modifiable once the file installed?! Can this be done through C#?!

EDITTED;

           wamp_url = openFileDialog1.FileName.ToString();
           String EnviromentPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);
           StreamWriter outfile = new StreamWriter(EnviromentPath + @"\Hex Technologies\wamplocation.txt");
           outfile.Write(wamp_url);
           outfile.Close();

You should not store your modifyable data files in the Program Files path. Use Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) or Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData)

The Program Files\… path is protected against modification by normal users on Win7+. It would be a bad idea to try to circumvent that protection.
