Ran into this recently. First one then four more users at a site, encountered it. This page:
has a fix with registry entries for version 2015. The fix reportedly works all the way up to the current (DC). Here’s Powershell to get the fix in; reportedly restart and/or reboot is required:
$RegistryPath = "HKLM:\SOFTWARE\Policies\Adobe\Adobe Acrobat\DC\FeatureLockDown" If (-Not (Test-Path -Path $RegistryPath)) { "Adobe Acrobat DC is not installed; fix not appropriate or needs modification." exit } cd $RegistryPath If (-Not (Test-Path -Path "cServices")) { mkdir cServices } cd cServices New-ItemProperty -Path . -Name bToggleAdobeDocumentServices -Value 1 -PropertyType "DWord" New-ItemProperty -Path . -Name bToggleAdobeSign -Value 1 -PropertyType "DWord" New-ItemProperty -Path . -Name bToggleAdobePrefSync -Value 1 -PropertyType "DWord" New-ItemProperty -Path . -Name bUpdater -Value 0 -PropertyType "DWord"
