can you post the path you are adding? my initial guestimation is that you might need to use a double slash, versus single slash, to get the correct syntax.
so instead of this: \hklm\software\mcafee
you would use this: \\hklm\\software\\mcafee
again, just a guess. ive never made a cag criteria based off of reg key.
From the Help:
In the first field enter a registry key of format <ROOT>\<KEY>\[VALUE_NAME].
- The <ROOT> must use the full root name, such as HKEY_LOCAL_MACHINE and not the shortened HKLM.
- The <KEY> is the key name under the root.
- [VALUE_NAME] is the name of the key value. If no value name is included, it is assumed to be the default value.
In the second field after the equal sign enter the data for the key value.
Tip: To copy a registry key for pasting, right-click a key in the Registry Editor (run regedit) and select Copy Key Name.
