I found this response in these forums and I was hoping someone could give more details:
Why didn't you try with a cab(cabinet) file. You can issue a digital certificate which can be understood by IE so that activeX automatically installs. RK
Is this saying I can issue a digital certificate to each PC that will automatically allow my users with restricted access on their pcs download the required ActiveX to edit KM files through the portal? Is there a good blog or guide that will explain the details of this process?
