Here: Windows 7 test system 32 Bit (in Virtualbox). You don't need 
Cygwin. (Although you _could_ install TexLive in Cygwin if you want.)

How have you tried to install it and which version? I have done an 
installation "over the internet" as described in 
http://www.tug.org/texlive/acquire-netinstall.html, installed it in a 
console (cmd) with "run as administrator" and then "install-tl 
-no-gui". Have you changed the standard installation path? (I have 
changed it, no blanks in path and no problems.)

Perhaps looking into your path variable could help? Does command 
"perl -v" work for a normal user in a new console window without 
switching in any TexLive directory structure (e.g. in the installer 
bin directory)? (Another perl version already installed?)

Is DEP (Data Execution Prevention) enabled for all programs? (It is 
advised to do so, e.g. current Adobe Acrobat security issue, 
http://www.adobe.com/support/security/advisories/apsa09-07.html, but 
sometimes this can have some side effects.) Enable/disable described
