I want to include the VBScript_RegExp55 library in my workbook, copies
of which will be used throughout the company. Generally speaking, is
this, including a reference like this (to a common file?), a threat to
portability? I don't know where or how this object is supplied. Do
all XP ports have a copy? Any comments?

Thank you.

Company env is Excel 2003. OS is XP and newer.
