WMIC gives a Win32 Error Access Denied
  Hi!

My current problem is that I need to create new users with password that never expire. In order to do that, I use the "net user" command line, but it does not allow to specify that the password never expires.

To do this last point, I use WMI, through the WMIC command line tool (installed with WinXP).
The strange thing is: if I do it from a DOS command line window, it works great.
If I do the exact same thing from a NSIS installer, it returns a "Win32 Error: Access is Denied"

The code:

    nsExec::ExecToLog 'net user NewUser "newpwd" /add /passwordreq:no /passwordchg:no /expires:never' $0


       ; ensure the password will never expire

        nsExec::ExecToLog 'wmic useraccount where name="NewUser" set passwordexpires=false' 

Anyone has any idea why that happens?

Cheers,

Wabiloo

Works fine for me for my own user, but I didn't try to create a new user. Have you checked for a race condition? Does it still say there's a problem with permissions when you execute the installer one more time only for set the password expiry?

Now, after some more tests, I realise that there is a problem with WMIC in general when used from my installers, not just when trying to set the password expiry flag.

The first thing I do in my installer is a simple "wmic quit" so that Windows can install WMIC properly, before it gets used to do things. Even that one gives me a "Win32 Error: Access is denied"...

The user under which the installer is executes is part of the Administrators group, so I really don't understand where the error is coming from...

Does it happen with every installer? Have you tried differently named installers? Which OS are you using? Have you tried it on other computers?
