The target operating system is not supported

Hi there,

sorry, but I am absolutely new to InstallShield and just have a maybe simple question.
My installation routine throws this error:
Errormessage
I try to install on a Win 7 Enterprise 64 bit system.
But in the Release Wizard I checked Windows 7:
Release Wizard

Can someone please help?

Thx in advance

There are a couple of things to note here.

First, the platform filtering in the Release Wizard does not affect runtime behavior. This setting changes what components will be included in a built project based on individual component platform/OS settings in the project.

Second, the string in the message box in the attached screenshot ("The target operating system is not supported") is not a string that is provided in InstallScript projects, it would have been added in the project. The display of this message box is likely controlled through the script in this project (which is the typical method of enforcing OS requirements at runtime for InstallScript projects), likely through the OnBegin or OnFirstUIBefore events. You can check the script in this project for any MessageBox/SprintfBox calls that are passing the displayed string. The script would need to be updated to support or restrict any additional operating systems.
