If an expert exists on this, I'm it, and I don't see any way that the "format or limitations of the connectevent" could be at fault.
If, as you say, it works on Windows XP but not on Windows 7, then that alone points to some cause outside of Window-Eyes, don't you think?
How are you running your wscript script? That is, are you using wscript or cscript, and are you running it from Explorer, from a command prompt, or in some other way.
Addressing the comments in your script: ConnectEvent "knows" that that event has two parameters. You should find that if you don't specify both parameters you get an error when you try to connect the event; do you?

Hi Steve, As I noted inside the email that the WMI does work as long as I am outside of the WE scripting environment. The WScript at the bottom works for both XP and Windows 7 but, the one inside my app only works for XP. So in saying that the only conclusion is the format or limitations of the connectevent. I had mentioned as a comment that maybe the passed in parms are not being passed in. It would seem that at least one should be but I am only guessing. I did try the connecteventwithparameters but which one and how. For I thought that any WMI event would automatically be passed in, but maybe that is the issue. But, it works as is on an XP machine and not the Windows 7 and the WScript outside of the WE Object Model both work all the time. I am at a loss and it seems to hinge on how the connectevent is taking and passing events here. So I am asking the experts on this, for it would seem they someone has come across this.

Bruce, I'm not a WMI expert by any stretch, but I am thinking that the added security settings in Windows Vista and above may be preventing your script from working as it did in XP. Do you notice any difference if you disable the UAC? Regards, Steve On 4/6/2012 3:37 PM, BT wrote:Hi Steve, All you scriptors below is an issue I have asked several on. The one that resides inside my Unintall app works on an XP but not on a Windows 7. In fact both work on the XP machine, only the one inside my app does not work on Windows 7. The .vbs file at the bottom works on the Windows 7 and alerts each time there is a change no matter the folder inside the LocalMachine hive of the registry. So the qeustion to ask is your connect object and event routines suppose to be the substitute for the standard script CreateObject ? Sincerely Bruce The first one is inside my Uninstall app around line 323 and does not work in Windows 7, below that is the script and does work in Windows 7 when run outside of any WE app, using WScript.
