"ConfigurationErrorsException" from "Settings.Default.Save()" in C# winform

Hi experts
I got an exception "ConfigurationErrorsException" when my program executed the statement "Settings.Default.Save()".

The details of the exception is: "Failed to save settings: An error occurred loading a configuration file: Could not find a part of the path 'C:\Users\dwong\AppData\Local\....'"

What puzzles me is that:
1. this problem happens only after I'd changed to a new hard disk (Windows 7, 32-bit).
2. this problem happens only when I run the program from the VS2008 debugger (release/debug modes).
3. this problem does *not* occur when the program is run normally (ie., after installing the program into the PC and run it directly)

Would it be a permission or security issue?

Thanks in advance.

Are you running Visual Studio as Administrator on Windows 7?

Thanks TheLearnedOne.
I'd checked "User Accounts" under the "Control Panel". In the 'Group' column, mine is 'Administrators'.
But how do I tell whether I am running VS as Administrator? Please enlighten.

When you run Visual Studio as administrator, by right-clicking on the link in the Start menu, or changing the startup for the link to Run as Administrator, the window title will include the text [Administrator].

When you are running Windows 7 with UAC enabled, your privileges are not administrator level, until you formally request it.

Thanks TheLearnedOne.

That solves my problem! I'd been running VS on Windows XP, and I didn't know there is such an option in Windows 7. Thanks again.
