I migrated my desktop earlier this year.  Now I discover that XWLan (widget) isn't available - add
widget showed it as grayed out.  I downloaded the zipfile, unzipped it, and invoked instwdt.cmd
which barffed on trying to copy xwlan.dll (?).

Ecenter classes showed xwlan, and widgets also showed something, although it wasn't visible.
Deleted that, closed Ecenter, and install worked.  Rebooted, and xwlan is still grayed out; it
doesn't show in widgets, although the dll shows in classes.

How do I get this going?
