Symptoms

Appeon Xcelerator plug-in cannot be loaded

Cause

This issue occurs if ActiveX controls are prevented from running on your computer. ActiveX controls may not run for one or both the following reasons:

1. Microsoft Internet Explorer may be configured to block ActiveX controls from running.
2. A firewall or a proxy server that exists between your computer and the Live Meeting conference center may be configured to block ActiveX controls.

Resolution

To resolve this issue, enable ActiveX controls in Internet Explorer. ?To do this, follow these steps:

1. Start Internet Explorer.
2. On the Tools menu, click Internet Options.
3. In the Internet Options dialog box, click the Security tab, and then click Internet
4. Under Security level for this zone, click Custom Level.
5. Under ActiveX controls and plug-ins, set all the following options:

Download signed ActiveX controls Enable or Prompt
Run ActiveX controls and plug-ins Enable or Prompt
Script ActiveX controls marked safe for scripting Enable or Prompt

6. Click OK, click Yes, and then click OK.

Note:
If you still receive the error message that is mentioned in the "Symptoms" section after you follow these steps, it is likely that a firewall or a proxy server that exists between your computer and the Live Meeting conference center is blocking the ActiveX controls. In this scenario, request that your Information Technology (IT) department stop blocking ActiveX controls to your computer or that your IT department add *.placeware.com to the list of trusted domains in the firewall or proxy server configuration.
