After a windows update, I was no longer able to lauch livemeeting using a RTC file.  I do have RTC associated with "MS office livemeeting router", and I have checked that ""do not save encrypted pages to disk" is unchecked.  I have uninstalled it and deleted the registry key for livemeeting before reinstalling.

But whenever I click on the launch.RTC link to start a livemeeting, I get the message "launch.rtc is not a valid Win32 application"

I have windows 7 operating system on my laptop that I'm trying to get this going on.

Any ideas to try?

Go to

Control Panel\All Control Panel Items\Default Programs\Set Associations

Locate the .rtc extension, and then select it.
Click the Change program button.
Click the Browse button, and then move to the following folder:
C:\Program Files\Common Files\microsoft shared\LiveMeeting Shared
If the list at the lower-right corner of the Open with box says Programs (*.exe; *.pif; *.com, ), change it to All Files (*.*).
Double-click Rtcrouter.dll, and then click OK.
Repeat stepsfor  .rtc-ms extension.
Click Close to close the file association box.

Thanks Ded9...I had tried this before and it didn't work...but perhaps your DLL was one I didn't try.  It now works!

I've tried everything in the MS KB article and I still get the launch.rtc is not a valid win32 application on a Win7 desktop with IE10, any other ideas?
