File visible as normal user but not as Admin

Question

I am building an universal updater for my company, and when I try to access a mapped network drive, the program throws a file not found exception when run as admin. When the file is run as a normal user the files are visible, but throws an Unauthorized Exception due to the fact that the files are copied to the Program Files (company policy).

Edit

The code that throws the FileNotFound Exception is FileVersionInfo fvi = FileVersionInfo.GetVersionInfo(rdrInner.GetString(2)); and the Unauthorized Exception is thrown by File.Copy(pi.RemotePath, pi.Path, true);

Mapped drives are part of the user profile, so you need to map the drive whilst logged in as the admin user. This is why using a mapped drive is a bad idea--can't you use a fully qualified UNC path instead? See http://msdn.microsoft.com/en-gb/library/gg465305.aspx for an explanation of UNC paths.
