The version information on the DLLs for the 1.4.1 pre-release have not been changed from 1.4. So, the easiest way to determine if you are running 1.4.1 or 1.4 is to open the BOMapper and if you have the "Customize Wizard" on the toolbar, then you are running 1.4.1. If you do not have the option on the toolbar, you are running 1.4. To upgrade, you will need to uninstall your current version of StrataFrame from the Add/Remove Programs of the Control Panel. Then download the 1.4.1 installation from the MyAccount area of the website and install it.
