To check for incomplete setup due to interference, see if the following shows anything amiss: $ /bin/ls -d -- /etc/postinstall/[!0z][!pqrst][!_]*.*sh \ > /*bin/*.new /usr/*bin/*.new 2> /dev/null | \ > /bin/egrep -vx '^/etc/postinstall/([0z][pqrst]_.*\..*sh|.*\..*sh\.done)$' I run this in my Cygwin profile with suitable wrapping to let me know if setup install or postinstall had issues, assuming Cygwin and coreutils are usable. You can fix these issues outside Cygwin by renaming any .../*bin/*.new files without the .new suffix, after renaming the original files to .old, when they are not open or being used; then running any /etc/postinstall/*.*sh scripts, whose names don't begin [0z]p_, under the required dash or bash shell, and rename with added suffix .done if the shell script completes successfully. This could be automated in a .cmd script using only cmd facilities and Windows utilities with some effort: it's getting a bit easier on Windows (Powershell is still mostly not standard/considered dangerous on corporate users' desktops), but still nowhere nearly as easy as with bash/dash/sh on Cygwin. -- Take care.
