I've done this with 1.7.10 still in place, once with portapps user (the failure case), and with my own regular (domain) user. Comparing the two outputs, there is an obvious ERROR_ACCESS_DENIED error in the failure case: 69 126706 [main] sh 3824 build_env: envp 0x61266AB4, envc 47 37 126743 [main] sh 3824 child_info::child_info: subproc_ready 0x234 589 127332 [main] sh 3824 seterrno_from_win_error: /netrel/src/cygwin-snapshot-20111219-1/winsup/cygwin/spawn.cc:692 windows error 5 59 127391 [main] sh 3824 geterrno_from_win_error: windows error 5 == errno 13 74 127465 [main] sh 3824 child_info_spawn::worker: CreateProcess failed, Win32 error 5 196 127661 [main] sh 3824 stat64: entering Any further hints?
