64 bit vs. 32 bit problem?

MarkBinder

I have a python script that searches a directory and subdirectories to find mxd files and then exports a pdf from the mxd. Here's the problem, when I run it using a 64 bit IDE some maps are missing a layer but when I use a 32 bit IDE the layer show up normally. I'm using ArcGIS 10.2.2 with the 64 bit geoprocessing package installed.

Why would layers show up in 32 bit but not 64 bit?

What is the storage type behind the layers? 64-bit processing has limitations on what types of backend storage types it supports: Background Geoprocessing (64-bit), see section on Unsupported data types.

Additionally, if data is stored in an enterprise GDB, you may need both 32 and 64 bit versions of the database drivers. We have to install a 64 bit Oracle client to access our Enterprise GDB datasets from 64 bit Background Geoprocessing scripts.

Good call. It turns out the data is stored in a personal geodatabase.

Thanks for the help!
