---+ Determining the Windows Serial Number

When installed on a Windows server or stand-alone PC, the APPX license is tied to the serial number of the C-drive of the machine on which APPX is installed. That is, even if you are installing APPX on the D-drive (or any other drive), it is still the C-drive serial number that is required.

To determine the serial number, exit to a DOS (command) prompt, and type the command "dir c:\ /p" (without the quotation marks, of course). This will display the first page of a directory listing for the root directory of the C-drive. The second line displayed will contain the serial number, like this:
<pre>Volume Serial Number is 1A2B-C3D4</pre>

That is the number that APPX requires, but it will be reformatted when entered on your license and when displayed by APPX. APPX makes three alterations to the serial number:
   1 Add a leading zero and hyphen
   1 Change all upper-case letters to lower-case
   1 Remove the hyphen between the two groups of characters
So, the serial number 1A2B-C3D4 will be entered and displayed in APPX as 0-1a2bc3d4.
*Note:* A foolproof way of determining that you have the correct serial number on any platform is to start APPX. Without a valid license, the system will display the serial number it finds on the machine.
