Python random number generator error. WindowsError: [Error -2146893818] Invalid Signature -


what wrong built-in python rng? line keeps crashing application

file "c:\python27\lib\random.py", line 113, in seed     = long(_hexlify(_urandom(2500)), 16) windowserror: [error -2146893818] invalid signature

the error occurs when try run python web application php's proc_open().

okay, turned out php problem, not os level, highly unlikely could've helped without code, i'll leave here if faces same problem.

this environment variable issue. when calling proc_open(), php uses operating system level environment variables unless specify $env fifth argument. error in case remembered incorrectly $env has specified, , used empty array value, overtook os level path definitions. removed $env , $cwd , worked charm.
