MS Access 2010 /pwd command line switch is missing

To automate a report from encrypted database  I used a free uility AutoHotkey.

Here is the source script, that I compiled to mydb.exe and then deleted
-----------------------------------------------------------------------------------------------------------------
run "C:\Program Files\Microsoft Office\OFFICE14\MSACCESS.EXE" c:\projects\mydb.mdb /cmd "auto"

WinWait, Password Required, , 3

sendinput {p}
sendinput {a}
sendinput {s}
sendinput {s}
sendinput {w}
sendinput {r}
sendinput {d}
sendinput {Enter}
return

-----------------------------------------------------------------------------------------------------------------

Then I used mydb.exe to run as a scheduled job.
