Same problem here with Acrobat Pro DC on Windows 2008 R2/Citrix XenApp 6.5
Since the update from 2015.006.30060 to 2015.006.30096 there is a new menu item in the "Help" menu, initially called "Login/Logoff" (loosly translated from German original "Anmleden/Abmelden") and after a while changes to two items called "Manage own account..." (Eigenes Konto verwalten...) and "Login" (Anmelden).
If you click the "Anmleden/Abmelden" a message will popup saying "Registration is initializing... Try again soon." (Registrierung wird initialisiert... Versuchen Sie es in Kürze erneut.)
Registry settings applied:
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\2015\FeatureLockDown] "bUpdater"=dword:00000000 "bAcroSuppressUpsell"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\2015\FeatureLockDown\cCloud] "bAdobeSendPluginToggle"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\2015\FeatureLockDown\cServices] "bUpdater"=dword:00000000 "bTogglePrefsSync"=dword:00000001 "bToggleWebConnectors"=dword:00000001 "bToggleAdobeDocumentServices"=dword:00000001 "bToggleAdobeSign"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\2015\FeatureLockDown\cSharePoint] "bDisableSharePointFeatures"=dword:00000001 [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Adobe Acrobat\2015\FeatureLockDown\cWebmailProfiles] "bDisableWebmail"=dword:00000001
JavaScripts:
// [Help - Repair Adobe Reader Installation]
app.hideMenuItem("DetectAndRepair");
