ActiveBarcode versions prior to version 6 are 32bit and can only be used with the 32bit (x86) version of Office. Starting with Version 6.0.0 ActiveBarcode supports 64bit and 32bit.
ActiveBarcode versions prior to version 6 have become legacy software and will be no longer supported by us. We highly recommend to update to the latest version.
