I'll try to stick close to the original points.

The values in HKCU are fine. Keyrings on removable media are easily handled by
editing gpg.conf. This allows portability across OSes by keeping OS-specific
path references in gpg.conf. The exact same PCMCIA card with keyrings works on
Windows, Linux, FreeBSD, Solaris, OSF1/Tru64, and VMS systems. I'd add OS X but
I don't have a Mac. The gpg.conf is practically the same in all cases, the only
differences being the semantics pointing to the files. HomeDir and gpg.conf
don't move. The keyrings move.
If only portability on a single OS is required, all that is needed is to define
GNUPGHOME as a user environment variable.

Then don't use it. You're 1 in a million. But, please don't extrapolate your
particular set of needs and preferences to the remaining 99.9999% of the user
base. The purpose of the installer is to produce a working installation of GnuPG
in a known valid configuration. Other than the ability and rights to run an
installer, there are no other system manglement skills called for or required.
The phrase "edit the Registry" will cause most Windows users without development
or system administration training to run in fear. We do not wish that result.

But you could with GNUPGHOME at either the user of system level, and/or
primary-keyring, keyring, secret-keyring, and/or trustdb-name directives in
gpg.conf. It is also an advanced configuration that is far outside the scope of
installing for and configuring a new user. This is the rare *exception* not the

I must say, I fully believe you are correct.

I concur. But there is still no need to edit the Registry. _None_.
You may, but it is not a requirement.

I hear your ranting, but it still won't make what you are saying correct.
Application specific DLLs go in the program's directory hierarchy.
Redistributable system elements that are newer may go under %systemroot%. The
Visual C 7.1 C runtime library, msvcr71.dll, is a good example. It wasn't
expected to be found on older machines, so its redistribution was allowed.
Your example of printer drivers being proof of your assertion is specious. Print
driver software is supposed to go there. It is expected to be used by all
programs on the system. What you didn't mention, was that the
monitoring/dashboard type widgets from the printer maker go in a separate folder
under %ProgramFiles%. Example: "C:\Program Files\Hewlett-Packard\HP OfficeJet
Series 600" with directories: Bin, Coverpgs, Data, Docs, Faxes, Help.
Ditto device drivers.
Further, the behavior of other installers is not proof of their correctness.
I hope Vista will seriously limit the practices you describe.

No, you're telling me your understanding of the Windows-development way colored
by your beliefs of what is best. Please check the Microsoft Windows Software

You may also want to poke around on MSDN:

Maybe. Maybe not.
The only way to be sure you get it is to place it in the same
directory as the program. Placing it in %SystemRoot%\system32 is *NO* guarantee.
If the DLL is not found locally, then a PATH search is started. An installer has
no way to determine what will or will not be found at program execution time.
Nor can it guarantee that directories in the PATH variable are ordered in a

The only way to 100% guarantee that the application finds the correct DLL is to
place it in the application directory. Things are even more fun with the spread
