Why are some pages unavailable in the Print dialog?
By default, the 64-bit version of Merge will be used on 64-bit capable systems. Unfortunately, not all printer driver suppliers currently supply 64-bit versions of their printer drivers. You might therefore see a message ‘The bundle XXXX could not be loaded because it does not contain a version for the current architecture’ for some settings pages in the Print dialog. If a new printer driver is available, try using that. Alternatively, you can run the 32-bit version of Merge by right-clicking on the Araxis Merge application icon, choosing Get Info, and then checking the Open in 32 Bit Mode checkbox.
