Is it possible to run 32bit and 64bit engines on the same system?

Question

Is it possible to run 32-bit and 64-bit engines on the same system managed by the same FME Server Core?

Please note that Safe Software's technical support for FME 2021.2 will end in August 2025. This means that 32-bit versions of FME will no longer be supported. To continue to receive technical support for FME, please upgrade your operating systems to 64-bit and download a newer version.

Answer

2022.0 or newer
As of FME 2022.0, 32-bit engines and operating systems are not supported. If you are running FME 2022.0 or newer, only 64-bit engines can be installed. Please see the FME 32-bit Windows Support article for more information about the 32-bit deprecation. 

2021.2 or older
If you are running FME 2021.2 or older, 32-bit and 64-bit engines can be installed and added to the FME Server core configuration. These engines can be on the same or a different machine. Please see the documentation for more information.
