The 64-bit version of our software requires a 64-bit operating system (e.g. a 64-bit version of Windows Vista or Windows 7) to operate whereas the 32-bit version of our software can be used on both 32-bit and 64-bit versions of Windows.

If you are using a 64-bit version of Windows (Vista or 7) and intend to work with large XML documents, then the 64-bit version of our software is right for you. However, database drivers and other issues may influence your decision to use the 32 or 64-bit version.

If you are using a 32-bit version of Windows (XP, Vista, or 7) then you must download the 32-bit version of our software. For further information on 32-bit vs. 64-bit click here . . .
