Hi Cecilia,
Modify all settings as you want them in your client.
\%userprofile%\AppData\Local\EPMOfficeClient\EPMClientPreference.xml
(path might be different depending on installation)
The specific settings you are after is:
<AutomaticRefresh>true</AutomaticRefresh>
<AlwaysAutoUpdateCharts>true</AlwaysAutoUpdateCharts>
<OfflineOnlyEPMReportsProtected>true</OfflineOnlyEPMReportsProtected>
Once you have set your EPMXLClientPreference.XML as you want to have it you need to distribute it to the clients (I do not think you can do that via the download center)
