August release: Unable to load the data model

I found now the problem, seems to be a common issue within our company with SSRS, reason is that some local policies are not set for the service account:

• Adjust Memory quotas for process
• Increase a process working set
• Lock pages in Memory

So created a domain service account, set the GPO for this service account that give the necessary privileges. Not sure if the SSRS installer could fix that, or at least during installation give a warning if the necessary privileges are missing.
