CheckProcess.exe returning 128
Here's my code:

.onInit

Function .onInit

  Delete $INSTDIR\install.log
  LogSet On

  InitPluginsDir
  File /oname=$PLUGINSDIR\CheckProcess.exe "CheckProcess.exe"

  ;Stop Services
  !insertmacro SERVICE "stop" "Service1" 0
  !insertmacro SERVICE "stop" "Service2" 0
  !insertmacro SERVICE "stop" "Service3" 0


  ;wait for services to fully stop
  StrCpy $1 'Service1'
  call SleepTilDone
  StrCpy $1 'Service2'
  call SleepTilDone
  StrCpy $1 'Service3'
  call SleepTilDone
  ...

And then the SleepTilDone function is:

Function SleepTilDone

    Banner::show /NOUNLOAD "$1 service stopping"

    keepSleepin:
    Push "0"

    IfFileExists $PLUGINSDIR\CheckProcess.exe 0 doneSleepin

    nsExec::ExecToStack "$PLUGINSDIR\CheckProcess.exe $1"
    Pop $0

    MessageBox MB_OK "The return value of CheckProcess.exe is:  $0" IDOK 0
    
    IntCmp $0 '0' doneSleepin
    
    Sleep 1000          ;sleep for 1 second
    goto keepSleepin    ;check again

    doneSleepin:        ;it's done
    Banner::destroy

FunctionEnd

As you can see by the SleepTilDone function, I was thinking that checkProcess.exe was missing, but I was wrong. CheckProcess keeps returning 128 which I have no clue what this is. 0 means the process is running, what does 128 mean? I use this same routine in a lot of installers and don't have any problems with it (even this exact installer on different machines), but on this one it hangs. Any help?

Thanks,
Eric

Exit code 128 means:

"No child processes to wait for"

I didn't think that was what I was doing. I just want to know if it's running or not (which in this case, it's not because the service doesn't even exist on this machine).

OK, figured it out:

The dynamic link library mscoree.dll could not be found in the specified path...

So, in other words, don't use checkProcess.exe on machines without the .NET Framework on them.
