We are trying to install a fresh version of Power BI Report Server at a client. The local account used to access the Report server is System Administrator on the box as well as on the Report server System level security (under site setting).
We cannot even see the New, Upload, Manage Folder buttons ... On other posts I have seen that the Sys Admin also needs to be a Content Manager. But I am not sure how to do that when I dont see "Manage Folder" button.
Any suggestion how to figure out which user would have access to get this working (The server was installed in tandem with client DBA who had access to create Report server databases - i would not want to bother him unless absolutely required).
Firstly, make sure that you are a member of the local Administrator's Group.
Secondly, add the Report Manager URL of Power BI report server to Local Intranet Zone in Internet Explorer following the guide in this similar blog.
Thirdly, open IE using "Run as administrator", then grant Item level permission to your account.
Since this was a client site, I had to use one local admins account (who had helped intially setup) to provide access through 'Manage Folder'
