The problem is, that @iamarden calls his "MySetup.exe" from a powershell window. If I do this I get the same error.  I'm not firm with powershell, but I suppose, that this is a problem of how powershell passes arguments to a calling process. I tested this with a sample suite in InstallShield 2016, which you can load in your InstallShield 2018 regards Markus ... View more

Okay, nur nochmal als Zusammenfassung: Dein "MySetup.exe" ist Deine InstallShield-Suite und an diese möchtest Du einen Wert für Deine Eigenschaft/Property " RabbitMQ_DbPath " übergeben ? Im Fall der Suite wäre das dann: MySetup.exe / RabbitMQ_DbPath:"C:\Databases and Logs\Database" Aber um das nochmal zu verifizieren, würde ich Dir empfehlen das so zu starten: MySetup.exe /debuglog"C:\Temp\Setup.log" / RabbitMQ_DbPath:"C:\Databases and Logs\Database" Unter der Voraussetzung, daß C:\Temp existiert, sonst einfach ein anderes Verzeichnis angeben. Dann in der Protokolldatei "Setup.log" nachsehen, wie RabbitMQ_DbPath gelesen wurde. Eventuell die Anführungszeichen und/oder inversen Schrägstriche maskieren. Gruß Markus ... View more

Okay sorry for the delay and for the case of a Suite the way is different the problem is the same. The receiving application needs " around the path with the space characters. But it is also important what type of "setup" is your "MySetup.exe". Is it a MSI-Project with a Bootstrapper or is it an other type of setup (InstallScript or something else). regards Markus ...

I also recommend to execute the installer with detailed windows installer logging (voicewarmupx), then you can better understand what is happening. regards Markus ... View more

Sure, use the default settings at step 7 "Local system account" and modify later. To modify later in the setup, you can also use the properties of the NT service object, see the help file ... prototype SetUserForNT_Service(STRING, STRING) /* Function definition: */ function SetUserForNT_Service(szUser, szPwd) OBJECT oObject; begin try set oObject = GetObject("My NT Service"); if (!IsObject(oObject)) then MessageBox( "Failed to get object reference.", INFORMATION ); abort; endif; oObject.DomainUserName = szUser; oObject.Password = szPwd; catch Sprintf( szStatus, "Unexpected Exception\n\nNumber: 0X%X\nDescription:" + "%s\nSource: %s\nHelp File: %s\nHelp Context: %d", Err.Number, Err.Description, Err.Source, Err.HelpFile, Err.HelpContext); MessageBox( szStatus, SEVERE ); abort; endcatch; end; This is just a modified sample from NT Services object help, not tested !! regards Markus ...

Just as information. From the product and license center there is the installation package "InstallShield 2020 InstallScript Objects" available (InstallShieldInstallScriptObjects.exe). If you install this package, then you can add the InstallScript object "NT Services" to your InstallScript project. With this object it is very easy to define your program as service. Just add the object to your feature and go through the wizard ... For standard cases you do not need any additional InstallScript code ... regards Markus ... View more

That's what I'm assumed, because in a basic msi project "add a service" is "built-in functionality" Do you use the installscript object "NT Services" ? regards Markus ... View more

you're welcome and that's exactly what communities are for  😀 have a nice day. Markus ... View more

You can also check the uninstall section for the presence of the access runtim msi package: regards Markus ... View more

I created a sample project which did exact this test. With empty "default value" it does not work, if I set a value to the default key, it works: regards Markus ... View more

Check line 426 in your installscript source "Service.rul". Check the existence of your service exe file before you call ServiceAddService. regards Markus ... View more

Okay I tried and I think the problem is, that in your "System search for Registry" the field "Registry Value: (Optional)" is empty. What is valid. But this does work only if the "Default value" is not empty. But in your case it is empty. From the windows installer help: Note that it is not possible to use the RegLocator table to check only for the presence of the key. However, you can search for the default value of a key and retrieve its value if it is not empty. Can you try to check for another key/value ? regards Markus ... View more
