Question

I am trying to read from a config file in ProgramFiles/MyApp but in Windows 7 it throws an exception for Access denied, it is the same and for a file in ProgrammData/MyApp:

fileStream = new FileStream(this.StorageName, FileMode.Open, FileAccess.Read);

Is not it allowed to read only from these folders?

it seems to be an UAC issue, and you should relocate your information according to nmahajan.

Quoting GTVic:

1 – C:\Users\username\Documents
2 – C:\Users\username\AppData\Local
3 – C:\Users\username\AppData\Roaming
4 – C:\Users\Public\Documents
5 – C:\ProgramData
Use for:
1 – data private to one user while logged onto one specific computer
the database files can be easily found by the user by browsing their Documents folder

2 – data private to one user while logged onto one specific computer
the database files are in a hidden folder but may be accessible by a skilled user

3 – data private to one user while logged onto any networked computer
the database files are in a hidden folder but may be accessible by a skilled user

4 – data public to any user logged onto a specific computer
the database files can be easily found by the user by browsing the public Documents folder

5 – data public to any user logged onto a specific computer
the database files are in a hidden folder but may be accessible by a skilled user
