Hi,I’m having an issue where PDF previews in Outlook do not work correctly after deploying Adobe Acrobat using the Customize Wizard.I configure all required settings in the wizard, then deploy via either setup.exe or the MSI. When I install silently using the command line in setup.ini (CmdLine=/sall /rs /smur) or via the MSI, the PDF preview in Outlook does not work. When I install interactively (with the GUI), the preview works perfectly. Has anyone encountered this issue or know what might be causing it?

Hi,

I’m having an issue where PDF previews in Outlook do not work correctly after deploying Adobe Acrobat using the Customize Wizard.

I configure all required settings in the wizard, then deploy via either setup.exe or the MSI.

When I install silently using the command line in setup.ini (CmdLine=/sall /rs /smur) or via the MSI, the PDF preview in Outlook does not work.
When I install interactively (with the GUI), the preview works perfectly.

Has anyone encountered this issue or know what might be causing it?

Hello,
Same issue here and found a solution that worked for me.
With Customization Wizard, go to “Direct Editor” section, then “Property”, find the “IW_DEFAULT_VERB” property and set the value to “Open” instead of “Read”.

You can now retry the silent install.

Since the PDF preview works with an interactive install but not a silent one, it may be related to a setting or component that isn't being applied during the silent installation. I’d compare the settings in the Customize Wizard with the installed version and check if the Outlook PDF preview handler is properly registered. You could also try repairing Acrobat after the silent install to see if that fixes the issue.

Hello Doryshe,

I looked into the issue, and these checks may help. After installing Acrobat, verify that the PDF Preview Handler is registered under HKEY_CLASSES_ROOT\.pdf\ShellEx\{8895b1c6-b41f-4c1c-a562-0d564250836f}. Also, check Outlook’s Trust Center → Attachment Handling → Previewers and make sure PDF Preview is enabled. If the registry entry is missing after a silent install, add a post-install registry repair. Also, check whether multiple Acrobat/Reader versions are installed, as they may cause conflicts. If your problem is not solved after using this, then you need to repair your Outlook PST file. Sometimes, when your Outlook files suffer due to any kind of issue, this issue also occurs. In such a case, you can use an Outlook PST repair tool to fix this issue permanently.
