Scripting

I found the below but it still shows PC's that have the software installed and PC's that don't have it installed.

select SMS_R_SYSTEM.ResourceID,SMS_R_SYSTEM.ResourceType,SMS_R_SYSTEM.Name,SMS_R_SYSTEM.SMSUniqueIdentifier,SMS_R_SYSTEM.ResourceDomainORWorkgroup,SMS_R_SYSTEM.Client from SMS_R_System  inner join SMS_G_System_COMPUTER_SYSTEM on SMS_G_System_COMPUTER_SYSTEM.ResourceID = SMS_R_System.ResourceId  where SMS_G_System_COMPUTER_SYSTEM.Name not in  (select distinct SMS_G_System_COMPUTER_SYSTEM.Name  from SMS_R_System  inner join SMS_G_System_COMPUTER_SYSTEM on SMS_G_System_COMPUTER_SYSTEM.ResourceID = SMS_R_System.ResourceId  inner join SMS_G_System_ADD_REMOVE_PROGRAMS on SMS_G_System_ADD_REMOVE_PROGRAMS.ResourceID = SMS_R_System.ResourceId  where SMS_G_System_ADD_REMOVE_PROGRAMS.DisplayName like "%Software X%")

AND

select distinct SMS_R_System.Name from  SMS_R_System where SMS_R_System.Name not in (select distinct SMS_R_System.Name from  SMS_R_System inner join SMS_G_System_ADD_REMOVE_PROGRAMS on SMS_G_System_ADD_REMOVE_PROGRAMS.ResourceId = SMS_R_System.ResourceId where SMS_G_System_ADD_REMOVE_PROGRAMS.DisplayName = "Software X")
