New applications are always becoming available that workers will require to enhance their job deliverables.  Some software is free, but the majority is license or subscription controlled. For some clients, we look after their licensing for them and when a new requirement is identified the additional software is purchased and deployed as needed.  It may be that there are restrictions in place that would prevent users from adding applications themselves, so a check with our Helpdesk first to make sure all is well and then permissions are granted to apply the application(s) to the system.
