There are several issues with Centra Symposium client operation. Most are related to Windows XP with Service Pack 2 and the recent (October 2004) upgrade to Centra Version 7.1. This blog repeats some and adds on to Larry's eariler entry.

The 5 most common trouble areas (not necessarily in order)are:
1. The CentraOne client version
2. The Java Virtual Machine version
3. The Active X control permissions
4. Browser Pop-Up Blocker
5. Windows XP Firewall

Details on settings for each of these is included below. Other things to be aware of are third party pop-up blockers, tool bars that include pop-up blockers and third party firewalls. Oh Yea, an important step is to make sure a microphone and speakers are actually attached to the computer.

A number of people are having a problem getting the Centra client to launch from their web browser. A procedure that has seemed to work in a number of instances is to reinstall the client and activating ActiveX. Below is a procedure I have used with several people, and it seems to work.

1. Click the Start button on your task bar and select "Control Panel", and then "Add/Remove Programs".
2. Select the CentraOne entry from the list of programs, click on it to select it; then click on the button to fully remove the program. Close the Add/Remove Programs window and the Control Panel windowl.
3. Launch Internet Explorer and click on the "Tools" menu.
4. From the pull down list, select "Internet Options"; then click on the "Security" tab.
5. Click on the picture of the globe named "Internet," and then on the "Custom Level" button in the lower portion of that window.
6. About the third major item in the list is "ActiveX Controls and Plug-ins." Proceed through that whole section on Active X being sure the various items are either enabled or set to "Prompt." In particular, be sure that the first one says to "Enable" automatic prompting for Active X controls. Then click on "OK" to close this window, and then "OK" again to close the Internet Options window.

7. Point your browser to http://centra.tamu.edu/main/tce and click on the System Check link just below the logo at the top of the page. Hopefully, the Centra client software will properly install, complete with the audio check.
