Following up on last week’s announcement of Adobe Acrobat and Acrobat Reader DC’s release, this article documents the silent install options for Reader.When it comes to deployment, you typically want a silent install so it is not hanging a computer waiting for somebody to click the ‘Next’ button. Command Line installation switches. I need to find command line swich installation options for Adobe Reader XI. I have tried the customization wizard, but I am not sure how to proceed with the MST file that is created.
Default viewer¶
Note
Windows 10 environments require using DISM and GPO configuration.
Keep in mind you may open even very large projects in this application without the loss of efficiency, CDR Open File Tool opens any document of CDR format without considering the state of input information. Moreover, you can use this software on any computer in the local area network and open corrupted drawings remotely. Cdr format files free download.
When Reader and Acrobat are installed on the same machine, you can choose which viewer is the default for PDF files. In some cases, this choice is critical as Reader has a built in Protected Mode which is more secure. For security details, see the Application Security Guide.
To select a default viewer, choose one of the following:
- Installer will decide which product will be the default: The installer decides which application should open PDFs based on the product to install and the values of IW_DEFAULT_VERB and LEAVE_PDFOWNERSHIP. In general, the install leans towards letting the more secure Reader be the default viewer unless a property or user choice overrides that decision.
- Make Reader the default PDF viewer: For Reader MSI modification only. Sets IW_DEFAULT_VERB to Read.
- Make Acrobat the default PDF viewer: For Acrobat MSI modification only. Sets IW_DEFAULT_VERB to Open.

IW_DEFAULT_VERB is written to the MST file and doesn’t exist in the installer tables by default. It can also be used on the command line or in the Setup.ini file.
Choosing a default PDF viewer
Property interactions¶
IW_DEFAULT_VERB interacts with the Adobe property LEAVE_PDFOWNERSHIP.
NO
allows the new install to own opening PDFs. LEAVE_PDFOWNERSHIP is often used for silent installs where the usershould not be asked to select a default PDF viewer.- YES prevents the new installation from taking over PDF ownership if PDF is already owned. However, if the PDF mimetype is currently un-owned, take ownership.
- If this property is unset or not present, the current install assumes ownership.
Locking PDF ownership¶
By default, users can select the default handler through the UI. However,administrators can lock the feature by setting
[HKLMSOFTWAREPoliciesAdobe<product><version>FeatureLockDownbDisablePDFHandlerSwitching
to 1 so that end users cannot change the default handler.
