Inform them that it takes 2 weeks to process software installation requests.
Make a ticket noting what you did. Put in in the Tech Services.Computer Labs.Software request area and the work type as Information. Be sure to change the group back to TechSvcs-Help Desk and assign it to yourself. You can then resolve the ticket. The request form goes directly to ICS and they will create a ticket to actually process the request.
