Problem

Error (in Event log) when stating Studio service:

"Service cannot be started. System.Exception: Unable to configure class [Aquima.Studio.Server.UserAccess.Xml.XmlUserProfileDao, UserAccess]: Root element is missing."


Solution

  1. Check your security settings
  2. Location of files: Install directory....\Studio\Configuration\Security\UserProfiles
  3. UserProfile may not contain empty xml files
  4. Remove or adjust corrupt xml files
  5. Restart Studio service
  6. Check event log

Note
The default value for admin.xml should be:
<?xml version="1.0" encoding="utf-8"?>
<?ProfileVersion 2.0?>
<Profile>
<UserName><![CDATA[admin]]></UserName>
<RecentlyOpenend />
<ListViewConfiguration />
</Profile>
