If formats you need are missing from the format gallery then you have probably installed a 64 bit version of FME. See the format comparison chart and select Compare By: Platforms

The rule on a 64 bit machine (Microsoft's rule really) is

• 64 bit applications need 64 bit libraries
• 32 bit applliations need 32 bit libraries

So a 64 bit FME requires 64 bit libraries of any third party software that you are planning to read/write. Many other software vendors do not yet have 64 bit libraries available for their software - ArcGIS Geodatabase and Geomedia being two of them. Consequently our 64 bit FME cannot access ArcGIS Geodatabase or Geomedia formats until these become available. However 64 bit FME can work with a 64 bit Oracle client to read Oracle databases. ArcGIS SDE is also available as 64 bit libraries which can be used by a 64 bit FME

32 bit FME can run on a 64 bit machine but it needs 32 bit libraries to access the third party software - this is why we can access the ArcGIS Geodatabase and Geomedia formats from the 32 bit FME. Also to get at the Oracle databases we require a 32 bit Oracle client - see the rule above.

In general we recommend to customers to continue to use the 32 bit FME until the full complement of formats is supported. With 32bit you will see significant performance improvements due to the 64 bit architecture.

There should be no issues with having a 32 bit and a 64 bit Oracle client on the same machine - we search for the correct library to load.

To use the 64 bit ArcSDE libraries with a 64 bit FME you will need to put the required SDE libraries where we can find them.Instructions for this are in artcle SDE Libraries for 64 bit FME reading 64 bit SDE.
