I cannot seem to find any documentation as to whether or not 64-bit background geoprocessing is native to ArcGIS 10.2. Or, is a separate download and install required as in 10.1? There were rumors prior to the 10.2 release that 64-bit background geoprocessing comes pre-installed with the upgrade/download. Is there an authoritative reference on this subject? No relevant system information is available on my Arc Administrator configuration information.

There is an option in the ArcGIS 10.2 Desktop Install for 64bit background Geo-Processing.

    Would the 64-bit geoprocessing show up on Arc Administrator if it were active? Or, what is the best method to confirm its existence?

  • See Using geoprocessing options to control tool execution resources.arcgis.com/en/help/main/10.2/index.html#//… as has an option for "Execute in the background or foreground"

    I am pretty sure background geoprocessing can exist without the 64-bit download.

    You can also check for the existence of C:\Python27\ArcGISx6410.2

In response to the answer which suggests to turn off background geoprocessing, I will just mention that if you do this you will negate the very purpose of the 64-Bit Geoprocessing installation. In order to take advantage of the 64-bit capability that this installation offers, you MUST have background geoprocessing turned on. Here are a few quotes (with sources) to back this up:

Also, if you are running ArcGIS under 8.1 (not yet officially supported, but it runs), you may want to TURN OFF background geoprocessing as it throws exceptions running tools that work fine when it is turned off. Don't know whether this is an artifact of some as yet unresolved incompatibility with 8.1 that will be fixed down the road.

    Did you mean Windows 8.1?

I had the same problem but did not have the installation setup program that provided me with the screenshot attached in the first answer. Here is a link to the 10.1 service pack 1 that has the option, but I don't know whether this will cause problems when installing on 10.2.

  • I have not tried this but I suspect that it would cause problems.
