Hello Marco,
This message is displayed by the OS (not ITCM) and occurs because your software package is trying to display a message on the screen. Because of the way Windows allocates user sessions, it cannot directly interface with the user’s screen because the package installation is running in a different session. This is a normal situation with current Windows releases. The dialog will not go away until you either close it or view the message.
You can prevent this message by ensuring your installation procedure runs in silent mode. This is highly recommended. You should ensure that all dialogs are avoided, and all text output is redirected to $rf if possible, which will be uploaded to the job output tab so you can see the result of your job.
It is likely, based on your description of events, that the installation displayed some error message and exited without performing the installation. However it looks like it returned an exit code 0, which indicates to software delivery that the package was successful.
If you need help creating packages you could either open a support case, or ask more questions on the communities. Also there are a lot of resources already published on the communities which may help. Please look through what is available so you can learn how to create a package successfully.
