The application was unable to start correctly 0xc0000142 CreateProcessWithLogonW

I have a block of of code

if(!CreateProcessWithLogonW(
    szUserName,
    NULL,
    szPassword,
    LOGON_WITH_PROFILE,
    L"C:\\Windows\\System32\\cmd.exe", // file to execute
    NULL,              
    NORMAL_PRIORITY_CLASS | CREATE_BREAKAWAY_FROM_JOB,   // creation flags
    NULL,              // pointer to new environment block 
    NULL,              // name of current directory 
    &si,               // pointer to STARTUPINFO structure
    &pi                // receives information about new process
    )){
        ReportError(L"Create Process");
    }

ReportError is not invoked, but csrss.exe pops up with

What am I doing wrong?!

The username and password ARE correct.

The code you posted works for me if I skip the calls to LogonUser, DuplicateToken and ImpersonateLoggedOnUser. You don't want to impersonate another user in order to call CreateProcessWithLogon since it basically does that for you, so just remove all that logic to do the impersonation.

Impersonating a user could also cause your program to be unable to launch an application at all if the target application requires a higher level of privilege than the user has.
