Setup fails with 1.7 upgrade attempt

[chethcoat@oplink.net]

I can find no direct information on this problem anywhere, so now I'm
writing you.  My computer is an Intel Pentium(R) 4, 3.4 Ghz and 1GB
RAM.  The OS is MS Windows XP 2002, SP2.  I've been happily running
Cygwin for 8 years, and it looks like it's time to upgrade to Cygwin
1.7.

I suddenly cannot run Cygwin setup.exe.  I've downloaded it several
times from various locations, and each time I run it, it fails at or
during downloading the mirrors.lst step with a popup window from the
Microsoft Visual C++ Runtime Libray saying:

<quote>
Runtime Error!

Program: C:\cygwin\setup.exe

This application has requested the Runtime to terminate it in an
unusual way.  Please contact the applications's support team for more
information.

Here is the contents of /var/log/setup.log.full after a recent attempt:

These clues hint at several possible problems:  An unexpected request
to terminate setup.exe; an unusual way of terminating it; can't open
i/o streams; user [who, me?] has no backup/restore rights; could not
open Service control manager.  I do not know if these problems are
independent or somehow connected, and I don't know what to do now.

One irritating note:  There is no way I can figure out to get
setup.exe tell me what version of Cygwin it thinks it's installing.
How can I verify that the current setup program on the Cygwin web page
is for 1.7 and not 1.5?

I've been depending on Cygwin on my Windows installation for years and
I don't want to lose it now.
