The ActiveX Installer Service is a new service in Windows Vista that handles installation of ActiveX controls by standard users. Standard users cannot install ActiveX Controls until this service is installed, running, and configured with a whitelist of Approved Installations Sites.
1. To install and start the ActiveX Installer Service
Follow the instructions in this article: Install the ActiveX Installer Service, by Tony Northrup on Vista Clues.
2. Configure ActiveX Installer Service to install EZTwainX
(Based on an article by Gabriel Lozano-Moran on Pointerx)
Once you have installed and started the ActiveX Installer Service as described in step 1, you must tell the ActiveX Installer Service which websites to accept controls from.
- Open the "Run" dialog: <Windows key> + <R>
- Enter the following command to open the Group Policy Object editor: gpedit.msc
- Click on "OK"
- Navigate to:
Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windowss Components -> ActiveX Installer Service - Double-click the administrative template "Approved Installation Sites for ActiveX controls"
- Click on "Enabled"
- Click on "Show"
- Click on "Add"
- Enter your host url. Ours is http://www.dosadi.com
- Enter the following comma separated value list: 2,1,0,0
The first number is for trusted ActiveX controls (meaning a control coming from a trusted site) , the second is for signed ActiveX controls and the third is for unsigned ActiveX controls.
The possible values are:
0: do not install
1: prompt user to install
2: silently install
Note that a silent install is never allowed for unsigned ActiveX controls. - Click on "OK" until you are back to the Group Policy Object editor, and exit.
