Note:

Starting with the November 2020 release of Acrobat DC, Microsoft Visual C++ 2010 redistributable package is no longer bundled with the Acrobat DC installer package. You have to install it first from the Microsoft website to enable the PDF conversion from AutoCAD.

When AutoCAD is not installed on your computer and you try to convert an AutoCAD file to a PDF file using Adobe Acrobat, you see the following alert messages:

Before October 2019 release of Acrobat DC

Alert

To disable the alert, follow steps in Solution 1, below.

Post October 2019 release of Acrobat DC

Conversion of AutoCAD files to PDFs is disabled

To enable the AutoCAD to PDF conversion, follow steps in Solution 2, below.


 

Solution 1: To disable the alert, create a feature-specific registry key on Windows as follows:

  1. Quit Acrobat application if it's already running.
  2. Open the registry editor -  go to Run (Windows menu + R), type regedit.exe in the Open field and click OK.
  3. In the registry editor, based on your installed version of the product, go the version-specific location listed below, and create the key FeatureState at the location; the key may not be present by default.
    • For Acrobat DC (Continuous):
      Location: HKEY_LOCAL_MACHINE\SOFTWARE\(Wow6432Node)\Adobe\Adobe Acrobat\DC\FeatureState
    • For Acrobat DC (Classic - Acrobat 2017):
      Location: HKEY_LOCAL_MACHINE\SOFTWARE\(Wow6432Node)\Adobe\Adobe Acrobat\2017\FeatureState
    • For Acrobat DC (Classic - Acrobat 2015):
      Location: HKEY_LOCAL_MACHINE\SOFTWARE\(Wow6432Node)\Adobe\Adobe Acrobat\2015\FeatureState
  4. Under FeatureState, create a key of type DWORD and name it bSuppressODADialog. Change its value to 1 (one).
  5. Close the registry editor.

Solution 2: Install Microsoft Visual C++ 2010 Redistributable Package, and create a feature-specific registry key on Windows to enable AutoCAD to PDF conversion as follows:

  1. Quit Acrobat application if it's already running.
  2. Go to https://www.microsoft.com/en-us/download/details.aspx?id=5555. Click on the Download button, and run the installer to install Microsoft Visual C++ 2010 redistributable package.
  3. Open the registry editor -  go to Run (Windows menu + R), type regedit.exe in the Open field and click OK.
  4. In the registry editor, based on your installed version of the product, go the version-specific location listed below, and create the key FeatureState at the location; the key may not be present by default.
    • For Acrobat DC (Continuous):
      Location: HKEY_LOCAL_MACHINE\SOFTWARE\(Wow6432Node)\Adobe\Adobe Acrobat\DC\FeatureState
    • For Acrobat DC (Classic - Acrobat 2017):
      Location: HKEY_LOCAL_MACHINE\SOFTWARE\(Wow6432Node)\Adobe\Adobe Acrobat\2017\FeatureState
    • For Acrobat DC (Classic - Acrobat 2015):
      Location: HKEY_LOCAL_MACHINE\SOFTWARE\(Wow6432Node)\Adobe\Adobe Acrobat\2015\FeatureState
  5. Under FeatureState, create a key of type DWORD and name it bEnableODAWorkflow. Change its value to 1 (one).
  6. Close the registry editor.
