I tried to install an app on SP 2013 when I got this message:
It is my developer server for a school project so I have all the privileges needed.
When I Googled the problem I found this page that explained how I should solve the issue http://www.sharepointalex.co.uk/index.php/2012/11/enabling-sharepoint-2013-apps/
But this link is on a high level and I did not understand it so I continued to this site: http://msdn.microsoft.com/en-us/library/fp179923%28v=office.15%29.aspx
My problem here is that I can't find "Under Application Management, select Manage services on server"
On http://social.technet.microsoft.com/Forums/en-US/77f7f5d3-7ede-4107-9932-c5b9f04c3a25/the-link-to-manage-services-on-server-is-missing-from-the-central-administration-page?forum=sharepointadminprevious&prof=required they said I should start the IE as administrator but I don't understand which program IE stands for.
Please help me so I can get the appcatalog working!
