I keep getting the following error when I try to edit SCCM reports. 
  
I downloaded and installed reportbuilder 3.0 on my deployment server and my workstation. I changed the registry to point to 3.0, restarted server, and ran as admin. 
  
Regkey that changed: “HKLM\Software\Wow6432Node\Microsoft\ConfigMgr10\AdminUI\Reporting\ReportBuilderApplicationManifestName” 
  
I even reinstalled as the Local Admin account. 
Same error. Anyone have any ideas on what else I may need to do?
