How to install Dynamic Web TWAIN ActiveX for web application end users?

After you deployed the ActiveX properly on your web server, the IE browser will prompt users to install the AcitiveX Edition of Web TWAIN. Please follow the steps below to finish the installation:

  1. Check the security settings of IE on the client machine and verify the following security settings are set to “Prompt” or “Enabled”:
  2. 1) Download signed ActiveX controls
    2) Run ActiveX Controls and plug-ins
    3) Script ActiveX controls marked safe for scripting

    The dialog box of the security setting can be launched from menu Tools > Internet Options. Then select the security tab.

    NOTE: Normally, you don’t have to check the above settings since the default setting of IE works well already. But if the control cannot be installed, you can then check the above options to troubleshoot.

  3. When accessing the web page on a client machine, you will be asked to install the ActiveX control. Click to install the control.
  4. Click the Install button.
