Question

Unable to install active X control - blocked by add-on manager in IE

Asked by: TeamLink

I am trying to install an active x control on my PC which I need to run a web based app on my intranet.

When I try to go to the page to install the active X component, I get the usual IE warning toolbar at the top (depite me having the site URL in trusted sites, and having active X security set to allow for every setting).

This isn't really a problem, I click and then choose to install. But, when I do that, I get a bubble at the bottom of the screen saying that the add-on has been blocked, and asking me to use the add-on manager to allow access.

As the component hasn't even been installed yet, I can't do that, as it doesn't appear in the list of add-ons in the manager interface!

how can I configure IE / my PC to allow installation of this component?? I have checked the group policy for the add-on manager, and this is all set to "not configured" both at user and at machine level.  I've tried various settings in group policy aswell, including setting "Deny all add-ons unless specifically allowed.." to be disabled.

Help, this is driving me barmy!

I am using IE 6 on XP Pro, Service Pack 2.

Thanks,

Phil

"I get a bubble at the bottom of the screen saying that the add-on has been blocked, and asking me to use the add-on manager to allow access."

Is there a standalone Antispyware program running, like Spybot's Teatimer, or Spysweeper?  Can you tell what program is giving you the bubble?

What AV is on your machine?

 

by: TeamLinkPosted on 2006-08-07 at 09:28:03ID: 17265000

no, the bubble is just within IE. On the status bar.

I have symantec corporate AV.

Thanks.

Try disabling Symantec before intalling the component, assuming you trust the component

 

by: mtz1of4Posted on 2006-08-09 at 05:01:48ID: 17278132

Can you tell Symantec to accept this ActiveX control and remember your decision.  I don't use Symantec so can't point you to the exact preference or option.  I believe it would be under Browser Security.

You should also confirm that the Security setting for your Local Intranet is set to Medium in Internet Explorer.

Note - From the Ad-on Help File.
"Unblock a publisher
To unblock a publisher

Open Internet Explorer.
On the Tools menu, click Manage Add-ons.
On the Blocked list, click the add-on for the publisher you want to unblock.
Near the bottom of the dialog, click Allow.
 Note
Unblocking a publisher will enable all add-ons that are digitally signed by that publisher on your computer
 Notes
If (Not verified) is displayed in the Publisher column, the add-on itself is not digitally signed even though the program that installed it might be.
Some add-ons might have been disabled by an administrator. In that case, the add-on will not show up on the list of add-ons, or you will not be able to enable it. In order to use the add-on the administrator will have to enable it. "

So are you part of your IT dept. or do you have an Admin that truly controls these machines?

Hi,

Sorry for the slow response - so much going on, so little time!

Anyway, tryed disabling symantec, this didn't help - also, other PC's on the network with symantec installed can install the active x no problem.

Thanks for the comment mtz10f4. Yes I am the system admin on the PC. Those instructions regarding unblocking the publisher do not help - the publisher is not blocked, and there is no obvious option in here to allow publishers that have not yet been blocked!!

Thanks for the help so far.

Phil

According to this page, you should be able to manually allow the activex control.
http://www.windowsitpro.com/eContent/securitypartner/index.cfm?action=Article&RD=1395&ED=1&articleid=49207
This article is aimed specifically at networks that use SBS 2003, which comes with Windows SharePoint Services, Microsoft Outlook Web Access (OWA), and other SBS 2003 features that use IE add-ons to function. However, you can take similar steps in an enterprise network if you're running these same features or products.
See the page for complete instructions but the gist of it is.
STEP 1: Find the GUID of the Add-ons That You Want to Allow
To put ActiveX controls on a Group Policy white list, you first must discover which controls your users need. Then, you must discover each control's Class ID so that you can type it into your Group Policy Object (GPO).
STEP 2: Add the GUIDs to the GPO's Allow List
After you have the GUIDs, you can add them to a GPO's allow list. On an XP SP2 client, open the most recent version of Group Policy Management Console (GPMC). Alternatively, you can download the XP SP2 Administrative Template (.adm) files and use them with GPMC on your server. Of course, if you already have Windows 2003 SP1 installed, the GPO entries that were new in XP SP2 are already included.

And from http://www.computerpoweruser.com/editorial/article.asp?article=articles/archive/c0412/57c12/57c12.asp&guid=
To see all the add-ons available to IE, use the drop-down menu to choose Add-Ons That Have Been Used By Internet Explorer. But there is more to see. Right-click the list's column headings to bring up a list of additional categories about these files you can add to the viewer. You will see fields that indicate when you last accessed the add-on, where its file resides on your hard drive, etc. Click any of these items to add the field to the add-on window.

This may not help if you can't see the control.
