If you configure the SFTP Root to anything other than its default of the root of the drive, such as C:\SFTP_Root, it takes the configuration, and it works, but it still insists on recreating the original C:\SFTP_Root folder every time it's launched, and it actually launches the product installer to do this. Version 1.0.4.9 on Windows 7 64-bit and Server 2008 R2 64-bit.
