Version 5 of ActiveBarcode has become legacy software. It will still run on your systems but will be no longer supported by us.
We highly recommend to update to the latest version. Especially if you need support it's mandatory to make sure to use the latest version.
The ActiveBarcode Control of version 5 is 32bit and can only be used with the 32bit (x86) version of Office. This also applies if you are using a 64bit (x64) operating system. The container (e. g. Office) of the ActiveBarcode Control determines whether you need the 32bit or 64bit mode. If you are using Office in 64bit (x64), you must upgrade to the latest version of ActiveBarcode 6. x, which supports both, 32bit and 64bit.
