Hello
It sounds like you are experiencing an issue with the security filtering of a Group Policy Object (GPO) that is installing a program on computers in your domain. One possible reason for this issue could be that the security filtering settings on the GPO are not being applied correctly to all computers in the domain.
One thing you could try is to check the security filtering settings on the GPO and make sure that they are configured correctly. You can do this by opening the Group Policy Management console, finding the GPO that you want to modify, and checking the security filtering settings in the details pane. Make sure that the security group or individual objects specified in the security filtering settings are correct and that they have the appropriate permissions to apply the GPO.
If you continue to experience issues with the GPO, you may want to try running the Group Policy Results Wizard to generate a report that shows how Group Policy is being applied to a specific computer or user. This can help you troubleshoot any issues with the GPO and determine why it is not being applied correctly.
