When I run: C:\Windows\system32>C:\cygwin64\bin\bash.exe --norc --noprofile "/etc/postinstall/000-cygwin-post-install.sh I get this back: 0 [main] bash 1956! child_info::sync: wait failed, pid 0, Win32 error 6 Even if I just run: C:\cygwin64\bin\bash.exe I get a popup saying "C:\cygwin64\bin\bash.exe is not a valid Win32 application" Any ideas?
