Hi all, I'm attempting to grab stdout/stderr output from C:\Windows\System32\tpmtool.exe using parameter getdeviceinformation. My code is as follows: $iPID = Run(@ComSpec & ' /k tpmtool.exe getdeviceinformation', "", "", $STDERR_CHILD + $STDOUT_CHILD) Local $sOut0 = "" Local $sOut1 = "" While 1 $sOut0 &= StdoutRead($iPID) $sOut1 &= StderrRead($iPID) If @error Then ExitLoop WEnd MsgBox(0, "Out0", $sOut0) MsgBox(0, "Out1", $sOut1) Exit but only returns (stderr output was also blank): Running from the run prompt with the same parameters gives an output I've tried piping output using >, clarifying the full file path, clarifying working directory, and a few other attempts. This is likely something incredibly dumb that I'm missing but help is appreciated!

Run ( "program" [, "workingdir" [, show_flag [, opt_flag]]] ) Your main issue was probably the lack of a valid show_flag. The parameter is optional, but if it is supplied, "" is not a valid value. This works for me: #include <Constants.au3> get_tpm_info_example() Func get_tpm_info_example() Local $iPid $iPid = Run("tpmtool.exe getdeviceinformation", "", @SW_HIDE, $STDERR_MERGED) If @error Then Exit MsgBox($MB_ICONERROR + $MB_TOPMOST, "ERROR", "Error running command - @error = " & @error) If Not ProcessWaitClose("tpmtool.exe", 5) Then Exit MsgBox($MB_ICONERROR + $MB_TOPMOST, "ERROR", "Timed out waiting for process to close.")
