it doesn't need a full; a delta (normal inventory) will work just fine.
Since it's been a few days, the view is probably already there. I'm sure some box somewhere has run an inventory, and has the regkey so it had something to say.
If not, the view isn't there; pick any random computer. Check it's registry, confirm the regkey exists with a value. Interactively, monitor inventoryagent.log (%windir%\system32\ccm\logs), probably using trace32.exe from the toolkit.
While monitoring the log, invoke a Hardware inventory. Watch for the line of select <yourvalue> from <yourwin32Whatever>. If the very next line is NOT "does not exist out", then that computer successfully had something to say. Wait a few minutes, and go check for the view.
fyi, view names are based on what you put in your custom "SMS Group Name" section of the mof edit.
question: what does your mof edit look like? Did you create it using Mark Cochrane's regkeytomof? or did you follow the wiki? Regkey mof edits can come in two flavors... ones like add-remove programs style which is for subkeys with common values, or the one I suspect you want, which is specific regkeys. If you made the wrong kind, that might be messing you up.
