General Description: If XC4000XL parts (rather than XC4000EX parts) have been installed, EPIC may report the following error:
Arc x/y offset file <unknown> not found
This occurs when I try to invoke EPIC on a 4028XL or 4036XL part.

This is a bug in the installer. The XC4000XL depends on files found within the XC4000EX data directory; one file (.axy) is not properly installed in the EX tree when the XL (but not EX) is selected by the user to install.
