Enumerate Values in VbScript throws an error

Question

I need to find a partial text (not full text match) inside the data of all the values of a subkey, or in other words: I need to find a firewall exception on the registry.

The problem that I have is that in my script the For says that the arrSubKeys object is not a collection, but it is! (the method itselfs instances a new array not?)

So I can't loop over the values and I don't know why I'm getting this error 'cause I've taken it directly from here in Technet.

I need help to solve this problem and to do the 'find partial text in datas' orders.

Const HKLM      = &H80000002
Const Key       = "SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\FirewallRules"
Const MatchData = "Action=Block|Active=TRUE|Dir=Out|App=C:\FTP Manager.exe"

Set objReg = GetObject("winmgmts:{impersonationLevel=impersonate}!\\.\root\default:StdRegProv")

objReg.EnumKey HKLM, Key, arrSubKeys

For Each Subkey in arrSubKeys
 Wscript.Echo Subkey
Next

Wscript.Quit()

UPDATE:

I've find my error I was trying to enumerate the keys instead of the Values, so now how I can proceed to match partial text in the data of each value?:

objReg.EnumValues HKLM, Key, arrValues

For Each Value in arrValues

...

Finally I did it, a generic usage script to launch it from the windows context menu (for example) to check the status of an Inbound or Outbound connection block of the specified file:
