Copy OMB.XLA, OMB.HLP and XLEN50.OMB to the Excel directory.
If you don't want to change xlen50.omb, make it read only. Saving the file
is slow, so I recommend this.
From Excel 5.0:
Add OMB.XLA through Tools\Addins\browse.
Click the toolbar button which appears, find xlen50.omb in the file dialog.
You now have an ini file so the next start is clean.
Click the ? button for an explanation on how to use the dialog.
