Trying to get eFax Messenger working on 2008 TS. Installed without a hatch in install mode. Logged in as an admin and I have a test .efx attachment in Outlook 2007. When I double-click on the .efx files, it wants to locate msgsplus.exe and install/re-install components, then it eventually opens the viewer. It does this every time I double-click on a .efx attachment. I can save the .efx localy, open the viewer directly, then open the .efx file from within the viewer, no problems. Anyone have experience with getting this working? Version is 4.4.
