NSF2X V1.3.0
Split NSF2X into 32bit and 64bit versions to handle mixed 32/64bit installations of Lotus Notes and Outlook. In any of mixed 32/64 bit installations, to export NSF to PST, NSF2X exports first to temporary EML files and then calls an external helper program of the right bitness to import the EML files into PST.
You should download the 'x86' version if your Notes client is 32bit and the 'amd64' if your Notes client is 64bit.
