Hi Linne,

Probably a bit late to help, and I suspect you've figured it out by now...but I would recommend against using "All Computers" or "All <anything>" as a collection for targeting Software Delivery.  A way which might work better would be a collection using the following logic (this will ensure that the machine has reported basic inventory already).  Maybe call it "Computers with Inventory posted" or something:

SELECT vr.Guid FROM vResource vr
JOIN Inv_AeX_OS_Add_Remove_Programs arp ON vr.Guid = arp._ResourceGuid 

Then, I would create a collection of "Computers with Adobe Reader 9.x" as so:

SELECT vr.Guid FROM vResource vr
JOIN Inv_AeX_OS_Add_Remove_Programs arp ON vr.Guid = arp._ResourceGuid
WHERE arp.Name LIKE 'Adobe Reader 9%' AND arp.Version LIKE '9.4.%'

Of course you can tweak the versions listed as needed, but be sure to leave the % in there as that is a wildcard to match any string.  Adobe is fairly consistent with their versioning now, but you'll still see regionalized versions sometimes.

Hope that helps!  I came across your post while looking for another one...
