How to set folder security permissions during installation

Hi all,

I hope this is in the right category. I have an application that I created which creates new folders under the install path:

'C:\Program Files\My Application\' and updates / deletes / installs files into.

Of course, whenever the program is run and any of these activities are attempted an access is denied message is shown. My question is how can I change the permissions for this folder on installation so all users can do these operations. I should also add that I'm kind of new to Windows development - any help would be greatly appreciated!

I had similar problem once but with database and not file, I'm not sure that it works but neverthe less I give you the first step

first you have to add an installer class to your application it is used when customised steps have to be taken during the installation

then you can override one of the two methods the Install() or the Commit() method. You set the IOPermission of your desired file as you like, the IOPermission could be declarative using attributes but in your case it is worth to use the imperative way
```
FileIOPermission oPermission = new FileIOPermission(FileIOPermissionAccess.Read, @"C:\Directory");
oPermission.AddPathList(FileIOPermissionAccess.Write | FileIOPermissionAccess.Read, "C:\Directory\file.extension");

Try this alternative and post me back, I'm intersted to know whether it works or not too.
Good luck

The installation would be on the local machine.

I have a question, the folder creation is on the local machine or in a remoting one?
