I'm trying to access the report manager, which in my case is located at
http://localhost/Reports. When I try to go there I get the following error:
User 'ComputerName\UserName' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed.
It seems that all the information I can find pertaining to this error has to do with trying to access the Report Server Web Service URL (which of course gives me the same error), and the solution to that problem requires access to the Report Manager so that's not very helpful. Also I've tried running my browser as an administrator as suggested by one solution but it didn't make any difference.
I am using Windows 8 and there is no domain. I am logged in as the same user that was used to install the operating system as well as all other software and it has sysadmin rights on the SQL Server Database Engine. Let me know what else you need to know and I'll post it asap.
