Since moving to Windows 7 x64 at work, Office Communicator 2005 will no longer allow me to do application sharing with other users on our domain. IM, file transfer, and video chat all work fine, but I consistently get the following message when I try to invite or accept an invitation for Application Sharing:
{Username} does not have data sharing session installed (or it is disabled) and is not able to accept your invitation.
Has anyone else experienced this problem or having working correctly?
