Thank you.
Now, however, I cannot download the trialware version. This is how I navigated in my attempt:
At "PGP Products | Symantec Corp." http://www.symantec.com/business/theme.jsp?themeid=pgp, I selected PGP Desktop Email link.
At "Enterprise Desktop Email Encryption | Symantec Desktop Email" http://www.symantec.com/business/desktop-email, I selected Trialware link.
At "PGP Desktop Email: Trialware - Symantec Corp." http://www.symantec.com/business/products/trialware.jsp?pcid=pcat_business_cont&pvid=desktop_email_1, I selected PGP Desktop Email Trialware link.
At "Symantec Marketing Campaigns" https://www4.symantec.com/Vrt/offer?a_id=109690, I selected Download Now button. For "Terms and Conditions" at the same URI, I selected the I AGREE button.
At different "Symantec Marketing Campaigns" https://www4.symantec.com/Vrt/vrtcontroller, I entered the same user ID and password that I use to login for this forum. I got the page at same URI with the message "Sorry! Your request could not be processed. Please try after some time."
I have been seeing this "Your request could not be processed." for at least the past four days.
Note that all of the navigation that I attempted was through Web pages that are clearly business oriented. Even the URIs indicate "business". I cannot find PGP Web pages on the Symantec site that are appropriate for individual, non-commercial, home users, which I am one.
