How do I check log?

I’ve been trying to export skeletal meshes and actions to UDK format, and I sometimes get the following message:

“Export Fail! Check Log”

Where is the log and how do I check it?

Thanks.

Not sure of the version of Blender you are using, but normally you check the text editor for a report, or use the -d, (for debug console), as a startup parameter in your blender.exe line. These areas used to give details of error reports, (or at least error codes for tracking problems). Also check the console as another viable location.
