Thanks for your suggestions. I want you to know that I really do appreciate
them. I have some replies to them below. (The replies, taken by themselves,
may imply that I'm being defensive, and that isn't my intention.)

That may be true, but the installer I use (Inno Setup) claims that when it
launches program at the end of the installation, it strips the Admin rights from
the launched program. (Older versions of Inno Setup didn't do this, and the
help specifically said to not include that option if the detected OS was Vista
or later.)

I agree, and asked him to do so via e-mail.

I use C++. However, all of LDView's registry access is (and has always been)
HKEY_CURRENT_USER. Also, I personally have never had problems running LDView
with UAC enabled, including running it from Program Files.
I sent him a build from the current source code, and that build apparently isn't
crashing, so it appears that the problem may have been some kind of bug in
LDView that has either been fixed in my source code since LDView 4.1, or is
masked.
