I would like to use some of the metadata tools in arcpy however they are 32bit. Is there anyway to run a 32bit geoprocessing task on server? We have a 32bit installation of ArcEngine on the same machine but just cannot work out if this is possible?
Server has existed only as 64-bit for a long time (there are no supported ArcGIS Server builds which are not 64-bit). You can certainly invoke a 32-bit binary as you wish, but there really isn't any such thing as a "32-bit geoprocessing task" any more.
