PGP, Ver. 10, is trying to install "missing components" after each system start but doesn't find the necessary files. What causes this behavior, how can I get rid of it?PGP has been around for a long time. It presently is a commercial program from Symantec. But there sis an open source community.
This Wikipedia article has some shortcomings, but gives the general idea.

Version 10 is given as both a FREE version or a paid version.
Please explain if this is a trial vision, a free version, or a paid version. If paid, you should get support from the vendor.

Here is a link to Symantec:

Here is an Open Source PGP

As ton your specific issue, there might be a conflict with you current version of Windows. Hard to sa without more details.This is unfortunately not an answer to my question. Additionally, there is no such thing like a free download of version 10 of PGP - or tell me if I'm wrong. I signed up with Symantic, the download of a trial version of Symantec Encryption Desktop Corporate from https://www4.symantec.com/Vrt/vrtcontroller is being denied, too. How to proceed now...?

Have you contacted Symantec ? ?
Does someone else use this PC or have access to it ? ?I contacted them, they did not reply. No one else has access to my machine.

And as I said above: The download of a trial version of Symantec Encryption Desktop Corporate from https://www4.symantec.com/Vrt/vrtcontroller is being denied, or, if right clicked, the site asks for a "Reference Code". I posted correspondingly here: http://www.symantec.com/connect/security/forums/pgp-desktop-email-and-netshare - the post doesn't show up, too. Strange company, to say the least...If it were me i would un-install it COMPLETELY...
NOTE: Most if not all Symantec apps need their own un-installer to remove properly at their site...
If you feel it's still an app that you need go with the Open source ver. which was mentioned above.
After all it started out originally as an open source project...The open source project links end up at Symantec - from where I can't download as I mentioned above. Seems to be a circulum viciosum :-)That's a bummer...same thing they did ruining all Peter Norton's fine products...
Oh Well...i'd get rid of it then.You would - but I don't give up yet :-) Can you try to download a trial or free version from Symantec? Maybe they don't like my European IP... But then, I also accessed their website VIA a proxy that creates an American IP - still no sucess...Sure...give it a go.
Maybe have someone here DLoad it and send it via an online file storage site...
Whatever works for you.
However i believe what's happening is it's detecting the previous broken install...THEREFORE the new one hiccups...which is why i suggested removing it completely using the Symantec un-installer.Up- and download from a file storage site is a wise idea. Tell me when it's done and name the corresponding link.

As for un-installing with a Symantec un-install tool: Can you upload this for me, too? Due to awkward living conditions, I only have limited Internet access , I have to WAIT until I'm sitting at a hot spot. That won't be before afternoon. For now, I say thank you and good bye - it's already 8:30 pm over here.I finally found a download possibility for a trial version. This one works now. Un-installing the old version however left a lot of trash behind. Could you please let me know where I can download the un-install tool for PGP that is reccommended by Symantec?The trial doesn't work either. I give up and change to another software.There are free encryption programs for personal use.
Any of these wound be a better choice that PGP.
One should not use PGP unless one fully understands what it brings to the table.
The free programs are almost as good and have no skeletons in the closet.
Maybe this is what you want:
