Following from the discussion https://www-secure.symantec.com/connect/forums/wha... in Sept 2012, the secure viewer (TEMPEST) functionality of up to V10.1 is essential for me. It allows viewing of encrypted files *without* generating a plain-text version that is stored on my disk and which I must then remember to find and shred. The Symantec guy 3 years go said he was going to put this to Management, but even in V10.3 the functionality has not been restored.
I have used this functionality for 20 years and don't want to live without it, so haven't upgraded from V10.1. But Windows 10 is now forcing an upgrade to V10.3, which allows only the reading of files encrypted in that way by an older PGP, but not the creation of such files. I could keep a separate Windows 7 just to be able to encrypt in this way, but it would be a major nuisance. Is there any other way to do this?
