I ran into an interesting problem recently with a client who was trying to upload a file for a Live Meeting in which she was the presenter. Her presentation was created in Power Point 2007 and had the extension .pptx. When she attempted to upload the file to Live Meeting she was prompted to install an ActiveX control to convert the .pptx file to a Live Meeting (.lmp) file. The problem came when installing the ActiveX file, when she clicked on the link to install the ActiveX file, the process started but then would come back with an error saying that the ActiveX control could not be installed.

After a little research I discovered that there is some kind of issue with a Java plug-in that seems to be causing the problem. My client had Java version 6.12 installed but I am not sure what other versions might be affected. Here are the steps that fix this issue:

• Go to Control Panel and open the Java applet.
• Click on the Advanced Tab and expand the Java Plug-in option
• Uncheck the Enable the next-generation Java Plug-in option
• Restart all browsers

If that does not work, installing the full version of Live Meeting may work also. See this thread for more information.
