When I installed Alfresco on a Windows 2008 R2 server I ran into an error while using the Easy Install.
The PostgreSQL installation would fail complaining about permissions on C:\Alfresco.
The solution was to add Modify and Write permissions for Users to C:\Alfresco as suggested by other postings.
But what about post installation? Are those Modify and Write permissions for Users still necessary for PostgreSQL?
Right now any User would be able to directly modify, write and delete things under C:\Alfresco.
