Server: 2008R2 64bit
SharePoint 2010: SP1 cum 12/2011 and also tried with SP2
SQL SSRS 2008 R2: Developer edition
I'm trying to upgrade SQL SSRS to 2012 using the msdn ISO including SP1 for 2012 Developer edition. On the installation wizard at the step which askes for the service account password, I recieve Access Denied with no other information. The failure is immediate.
I have confirmed that the password is correct. The service account is in use by other services and is a member of run as service. I've tried escalating the permissions all the way to Admin. I've also tried granting it sysadmin on the database server.
Is there anything else to try? I'm about to uninstall and reinstall, then fix my reports and subscriptions. This is a dev environment, but I expect the same will occur in production.
