Adobe support website states that Adobe Acrobat Pro is compatible with 64-bit versions of Windows. I am using Windows Vista Ultimate 64-bit and Acrobat X Pro, and I am missing the PDF tab from the file properties dialog box. This is because Explorer is a 64-bit program (since it is running on Windows Vista 64-bit). But if I do the same within the Open dialog box in Acrobat Pro I can see the PDF tab.
In Windows Explorer:
- Open Windows Explorer (Win+E)
- Navigate to Desktop.
- Right click on a PDF file.
- Click Properties.
See fi you can see the PDF tab in the dialog box that appears. If you are on 64-bit Windows Vista (maybe even Windows 7) you will not see this option.
However, in Adobe Acrobat X Pro:
- Open Acrobat X Pro.
- Click File, then Open (Ctrl+O).
- Navigate to Desktop.
- Right click on a PDF file.
- Click Properties.
Now you should be able to see the PDF tab in the file properties dialog box. Why it appears in Acrobat Pro but not when viewing the same dialog box from Explorer is because Acrobat Pro is a 32-bit software.
The change I want to see is that the PDF tab will be visible, regardless of if you are viewing it from within the Open dialog box in Acrobat Pro or from Window Explorer. You need to either provide a fully functional and full featured 64-bit version of Acrobat Pro, or you need to provide a working 64-bit Shell Extension for compatibility with 64-bit Windows and 64-bit Explorer, and keep Acrobat Pro as 32-bit only.
