Answer 1

// Use this to get the common directory
string CommonDir = Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);

// And combine it with your own. 
// On Window7 this will return "c:\ProgramData\YourCompany\YourProduct"
string YourDir = Path.Combine(CommonDir, @"YourCompany\YourProduct");

// And create the directory / ensure it exists
System.IO.Directory.CreateDirectory(YourDir);

There are other Special Folders you can get from the system, such as MyDocuments or Desktop as fits your needs best.
