Problem with exit codes

[Graeme]

Hi,

I have a problem in that one script runs successfully and gets to this line

MsgBox(0x40,$UpdateID,"Successfully installed update " & $UpdateID)
Exit(1)

This script was started by another at this point:

$InstallationResult = RunWait($ExeFileFullPath & " " & $InstallerParameters)
                    ProcessWaitClose(StringReplace($FileName,"mmupdate","exe"))
                    SplashOff()

If $InstallationResult = $DesiredResult Then
   FileMove($ExeFileFullPath, $FileFullPath & ".done")
   LogWrite("Update succeeded")
Else
                        ; the update failed... oh dear what shall we do?
   If 1 = MsgBox(0x21,$PrettyScriptName,"The update failed to install - try again another time?") Then
      FileMove($ExeFileFullPath, $FileFullPath)
      LogWrite("Update failed - will be retried on next launch")
                           
   Else
     FileDelete($ExeFileFullPath)
     LogWrite("Update failed - deleted by user request")
                            
   EndIf
EndIf

I had two problems - first

I had to put the processwaitclose in because otherwise the program would go onto the "update failed" msgbox before getting to the "update was successful" msgbox!

                                second

even with the processwaitclose it gives the $installationResult as 0 not 1 even though when it finally finished the first script the exit code must have been 1 as that follows after msgbox which shows?

Any ideas? Is it possible that 2 exit codes are produced??? Is it possible for $installationResult to be set before the program finishes?

Are you using #RequireAdmin on the real script?

[Graeme]

I use #requireadmin on the secondary script - the one that finishes with the Update successful msgbox but not on the other. It doesn't need it except in the rare days that there is an update.

Do you use it in the script that this line starts? "$InstallationResult = RunWait($ExeFileFullPath & " " & $InstallerParameters)"

[Graeme]

Yes, that's right.

That's why you don't get the exit code you want. When you use #requireadmin in a script, the script is immediately exited and then reran with a request to elevate permissions for it. Your RunWait sees the first exit, and doesn't know it has restarted.

Thanks for that!
