Problem with IE attach related to ObjCreate("shell.application")

[mLipok]

I have some problems with windows explorers.

Here is my testing snippet:

;~ #RequireAdmin

_Example()
MsgBox(1, '', '@error = ' & @error & @CRLF & '@extended = ' & @extended)

Func _Example()

    Local $oShell = ObjCreate("shell.application")
    If @error then Return SetError(1, @extended, 0)

    Local $oShellWindows = $oShell.windows
    If @error then Return SetError(2, @extended, 0)

    If $oShellWindows = Null Then Return SetError(3, 0, 0)

    Local $iCount = $oShellWindows.Count
    If @error then Return SetError(4, $iCount, 0)

    Return SetExtended($iCount,1)

EndFunc   ;==>_Example

Normally this should return in extended number of opened InternetExplorer + WindowsExplorer.

But in some cases I encounter a problem with this, as there happens situation when @extended returns 0 even if I had already opened IE.

Here is one of them:

I have some script which is working fine with IE on about 100 computers.
In this specyfic case this script starts his work, and after few minutes he stoped works.
All the time IE is still responsive, I can click on elements and go to specyfic places.

Restoring the script did not help because _IEAttach () does not work.
All you need to do is restart InternetExplorer.

 

As a result of all my investigation I had done you can see this script snippet above.
In my case My primary script was doing their job, but when he stops, IE was still responsive but this above snippet starts to return @error=0 and @extended = 0 when @extended should be at least =1 (this opened Internet Explorer instance)

QUESTION:
Has anyone already encountered such a problem?
Does anyone know any solution or has an idea for further diagnostics?

 

btw.
I have one solution which would fix it - I mean Windows reinstall, but this is not good solution, as I always like to know the esense of the problem.

 

EDIT:
I know you can say show the script........ this is not possible you have no access to this site, and about 100 computers works well, so this i not related to my script.

The more so that the problem is not related to my main scripts, and the problem is simply how IE behaves - which is illustrated by the above piece of code.

So the issue is that

$oShellWindows.Count

returns 0 when it should be returning some other value?

[mLipok]

Yes.
But imagine it, you run IE + explorer.exe, run your main script and then after few minutes $oShellWindows.Count returns 0 instead 2, but IE and explorer.exe is still responsive.

can you try to  repair IE installation?

also, on that system try the following to see if anything is corrupted on that windows install.

sfc /scannow

Please be more specyfic - what I should do ?

[Earthshine]

Repair Internet Explorer

Internet Explorer has stopped working, freezes, crashes, hangs in Windows 10/8/7

 

I would also do the sfc /scannow thing at an admin prompt

take a look at event viewer on that box as well to see what all the commotion is about, it should show lots and lots of errors. copy and paste here so we can do more troubleshooting
