>The key exists. I can see it with "RegEdit" I can open & delete it with "RegEdit" But not in code. I ran the ".prg" from "WestWind" The keys were created. But not deleted. I un-commented Rick's code for the deletion. But it failed.

Mike,

Try

DECLARE Integer RegOpenKey IN Win32API;
  INTEGER nHKey, STRING @cSubKey, INTEGER @nHandle
lnSuccess = RegOpenKey(lnOpenHKey, @lcOpenKey, @lnOpenResult)
