Thank you. I followed your directions and this allow me to download and install 6.5.2.725. I no longer have the problem of the program not opening. I can open without Run As Administrator.
On the initial open, Enpass immediately pops up a message that there is an update available. I ran that update to version 6.5.2.727 and the problem returned of not opening the program from Enpass.exe unless I Run as Administrator. So I cleared/deleted and reinstalled 6.5.2.725. I will keep this version and not upgrade to 6.5.2.727 because this is clearly where the problem resides.
Thank you for the direction to the download.
