How to stop automatic upgrade of Acrobat Reader 32-bit to Acrobat Reader 64-bit
If you have deployed the 32-bit version of Acrobat Reader, use the following procedure to stop the Acrobat Reader 32-bit application from automatically upgrading to the 64-bit version. Create the following registry key before the first launch of the application:
1. "Go mobile with your PDF's"
| HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\HomeWelcomeFirstMile\ | # |
|---|---|
| bEnableFirstMile | Disable = 1 |
2. "Work on the go with the Adobe Acrobat Reader app. (...)"
| HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\Workflows\cServices\cAcrobatApp\ | # |
|---|---|
| bAcrobatAppInstalled | Disable = 1 |
3. "Scan business cards, receipts, notes, (...)"
| HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\DC\Workflows\cServices\cScanApp\ | # |
|---|---|
| bScanAppInstalled | Disable = 1 |
4. To disable SharePoint integration:
| HKLM\SOFTWARE\Policies\Adobe\<product name>\<version>\FeatureLockDown\cSharePoint | # |
|---|---|
| bDisableSharePointFeatures | Disable = 1 |
5. The Adobe Reader DC Welcome screen can be distracting and also has online links to the Adobe quick tips website, tutorials, blogs and community forums. When the Adobe Reader DC Welcome screen is disabled the Welcome screen will not be populated on application startup.
| HKEY_LOCAL_MACHINE\Software\Policies\Adobe\Acrobat Reader\DC\FeatureLockDown\cWelcomeScreen | # |
|---|---|
| bShowWelcomeScreen | Disable = 0 |
6. For Reader, indicates whether the end user license agreement has been accepted by the end user (Reader only).
Acrobat uses the key EULAAcceptedForBrowser.
If the EULA is not accepted, the application cannot be used and the Updater is also prevented from running. Possible values include:
| HKEY_CURRENT_USER\SOFTWARE\Adobe\Acrobat Reader\DC\AdobeViewer | # |
|---|---|
| EULA | = 1 Don't show the EULA because it has been accepted |
7. Products that don’t provide the full set of features provide the user with the opportunity to upgrade. For example, Reader users can purchase additional tools and features, and Acrobat Standard users can upgrade to Acrobat Professional. To turn off upsell messages
| HKLM\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockdown | # |
|---|---|
| bAcroSuppressUpsell | Disable = 1 |
8. #
| HKLM\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\cServices | # |
|---|---|
| bUpdater | Disable = 1 |
| bToggleAdobeDocumentServices | 1 disables all Document Cloud service access. |
| bToggleWebConnectors | 1 When 3rd Party Web Connectors are disabled it prevents the configuration of Adobe Reader DC access to third party services for file storage. |
| bToggleDocumentCloud | 1 Disable Document Cloud storage. |
9. Disable in-product messaging
Acrobat products display messages on startup as well as in dialogs or in various areas of the UI. For Reader, messages can also appear when a document is opened. These messages may include information about other products, features, or services. To disable this feature, set the following:
HKLM\SOFTWARE\Policies\Adobe\Acrobat Reader\DC\FeatureLockdown
bDontShowMsgWhenViewingDoc
bShowMsgAtLaunch
bAllowUserToChangeMsgPrefs
