Help needed installing cygwin: may be ini file problem

I'm trying to install cygwin on my Windows 7 machine.

I get the setup by starting the install on http://www.cygwin.com/. I choose "Install from Internet" (which links to http://www.cygwin.com/setup.exe), then select successively in the Wizard:

• All users + Unix text files
• local package directory = C:\Cygwin
• direct connection
• download site = mirror.cs.vt.edu (I tried a few others and ran into similar problems; if there is one in particular someone highly recommends, I will gla开发者_如何学Godly try it).

I get a warning "The current ini file is from a newer version of setup.exe. If you have any trouble installing, please download a fresh version from http://www.cygwin.com/setup.exe", but as far as I understand, that's exactly what I just downloaded to start this. Then I get parse errors. I have no idea where I am going wrong, or where I would go to get the correct setup.exe. Any suggestions?

Delete the setup.exe that's on your hard drive and try again. Alternatively, try downloading from http://mirrors.kernel.org; I just tried it and it works for me. The new version should be 2.721 (as it appears on the spash screen).
