Hi David

The info for the current user profile is stored in the 'BaseSettings.xml' file located in the following location:

C:\Users\[USER NAME OF CURRENT USER]\AppData\Roaming\SDL\SDL Trados Studio\11.0.0.0

In here you should see something like this:

 <SettingsGroup Id="IUserSettingsService">

   <Setting Id="CurrentUserProfileFilePath">C:\Users\faziz\AppData\Roaming\SDL\SDL Trados Studio\11.0.0.0\UserProfiles\Builtin\Default.sdlprofile</Setting>

 </SettingsGroup>

So for my instance of Studio the 'Default' profile is enabled.

Here is the actual code I used to get a strongly typed object to represent that file:

XmlReader reader = null;

           try

           {

               reader = XmlReader.Create(_baseSettingsFile);

           }

           catch (Exception e)

           {

               PromptFailedToReadBaseSettings(e.Message);

               return;

           }

           ISettingsBundle baseSettings = SettingsUtil.DeserializeSettingsBundle(reader, null);

           ISettingsGroup userSettingsService = baseSettings.GetSettingsGroup("IUserSettingsService");

           Setting<string> currentUserProfileFilePathSetting = userSettingsService.GetSetting<string>("CurrentUserProfileFilePath");
