Request for a 64-bit version of GpgEX


First of all, a big thank you to everyone involved in creating Gpg4win! It’s a great product, and I really appreciate all the work put into it.

I am new here, so I apologize for my humble request:

Would it be possible to create a 64-bit version of GpgEX? I realize that this has been asked before, with a negative answer. (See and the subsequent messages in the thread.) However, as the number of users with 64-bit versions of Windows steadily increases, the usefulness of a 64-bit version of GpgEX increases as well.

I realize that there is a workaround, listed in the README. However, running “C:\windows\syswow64\explorer.exe /separate” in the released version of Windows 7 x64 does not work, and there seem to be no intentions to fix this bug. (This is a bug with Windows 7, not with GpgEX. For more info, see .) Because of this, the workaround does not work for many users of Gpg4win. (And, even when it does work, it is still somewhat unwieldy.)

So, would it be possible to create a 64-bit version of GpgEX? The shell extension is very handy, and it is a shame to be unable to use it in the 64-bit version of Windows 7. I am not a programmer, and so I apologize if this is a difficult request to fulfill. Thank you, however, for considering it!

Hi Alex,

just an off-topic question:
As I can’t manage at all (on different computers
first with Windows Vista Ultimate x86, now with
Windows 7 Enterprise and Ultimate x64) to get a
Gpg4win-installation that really works (actually
I think the reason is Kleopatra) I would like to
ask you if you can sign a text using the
clipboard and Kleopatra. At least this would
make clear that this is maybe no general problem
of Kleopatra but of me and my computers.

Not having a x64-version of GpgEx is not a real
problem - if one can’t use GPG itself … (OK,
although not tested I don’t think that I won’t
be able to sign and encrypt files using the
commandline without Kleopatra. But as I first
of all ‘just’ want to sign my outgoing and check
signatures of incoming e-mails using the
clipboard this is no help to me).
I even think of switching back to PGP itself as
I can’t use GPG anymore since quite a while
(problems with the WinPT now with Kleopatra).

Well, I routinely encrypt/sign and decrypt/verify files using Kleopatra. I just wish I could use GpgEX instead, so I don’t have to open Kleopatra manually and search for the file using the file dialogue, etc.

For email I use a rather old program, PMMail, to encrypt/sign and decrypt/verify my messages. I just set it to point to the same public and private keyring files that Gpg4win uses.

And for email I also use FireGPG (but PMMail is better for attachments). There are a few incompatibilities between PMMail and FireGPG…

Signing/verifying just a piece of text on my clipboard is not something I often do. I don’t know how to do with with Kleopatra, but I can do it easily with FireGPG or with GPA.

Hash: SHA1

This sentence is signed with FireGPG.
Version: GnuPG v2.0.12 (MingW32)
Comment: Use GnuPG with Firefox : (Version: 0.7.10)


Hash: SHA1

And this sentence is signed with GPA.
Version: GnuPG v2.0.12 (MingW32)


Yes, I realize that you don’t have my public key and thus won’t be able to verify my signature…

Does this answer your question at all?


Oh, now I see Kleopatra’s option for signing and verifying clipboard text. I couldn’t find it in the program itself, and it’s not mentioned in the Kleopatra manual – it’s accessible only by right-clicking the icon in the system tray. Intriguingly, the “Decrypt/verify…” option is grayed out whenever the Kleopatra window itself is open.

Anyway, yes, I can sign and verify text using this option.

Hash: SHA1

This sentence is signed by Kleopatra.
Version: GnuPG v2.0.12 (MingW32)


Again, apologies, as I know you don’t have my public key.


Oh, I’m running Windows 7 Professional (x64) and Gpg4win 2.0.1.

Sorry for the multiple messages!


Hi Alex,

thank you for all your answers.
I will have to try to get rid of all rests of the
Gpg4win- and GPG-Pack-Installations I have tried
the last months … I have always used the
uninstallation-routines provided but anyhow it
seems that too many things are left.

Maybe then I can try it again. But not only GppEX
isn’t x64-compatible; GPA is meant for 32-Bit-
systems too, isn’t it?
I guess that I will have to set up some virtual machines when I find the time to do so and then
to check the different tools and the different

FireGPG on Mozilla’s Add-On-Site is not Firefox
3.6.2-compatible. And installing an extension
from another source is an even bigger risk than
from Mozilla I suppose.

I tried to verify your signatures using the
clipboard but Kleopatra always didn’t say that
I don’t have your public key but that there are
no signatures. Again this confirmes to me that
Kleopatra is the problem, not GnuPG itself.
But as I already wrote: WinPT does not work either (german umlauts are changed while signing
via clipboard; the result is difficult to read
and the verification of the signed text always
fails. Years ago this already happened but got
fix back then. Now that problem is back but the
development of WinPt is suspended).

I guess I will give FireGPG a try and try to
get rid of leavings mayby left by WinPT and Kleopatra …

Thank you!

Best regards

Is there any progress for getting GpgEX working in Windows 7, 64 bit?


The shell was always very useful and its absence is one of greatest regrets since I changed to Windows 7, 64 bits.

Philip: you have confused me. I run Win7_Pro_x64 and use the shell often.

There are many programs, both FOSS and commercial, that seem to have a problem figuring out what ‘proper behavior’ is on Windows 64 bit. I have started testing WIN8, and see the same pattern, though the issues have changed slightly.

One thing that has not is that I can avoid the interface problems by firing up the shell and performing command-line operations. Could your security settings be set to refuse you that access?

William –

What I miss in Win7 64-bits is the ability to right click on a file in Windows Explorer and get a drop-down menu with the crypto options for that file.

I suppose you are referring to operation from the command line. I prefer to use the windows screen gui because that is where most of my other activity (music scores ) takes place.

This worked very well in WinXP. – I only went to Win7 because my XP box finally failed and I thought it would be a good opportunity to upgrade.

I can carry out all the crypto ops with Kleopatra but it is so slow to load (the slowest application by far on my PC) and various jobs hang up and need redoing from time to time. Not ideal.

“What I miss in Win7 64-bits is the ability to right click on a file in Windows Explorer and get a drop-down menu with the crypto options for that file.”

That’s also my point ! It was so convenient !
Sure, when needed I will open a command window and type the appropriate command (that I have not yet learnt by hart).
But right click was SO easier !

Thanks !

Well, well, well ! We’ve got it ! GpgEx is now here and seems to be working well in Windows7-64, since I installed the latest version of Gpg4win 2.2.0.

A big thank you to the developers.
