Step 2: Finish installation. Download free Adobe Acrobat Reader software for your Windows, Mac OS and Android devices to view, print and comment on PDF documents. The Database uses Reader DC because almost no one on the network has Acrobat Pro. Yesterday Adobe updated my 32-bit Reader to 64-bit without notifying me. It broke the Database because the necessary library was removed. I found the new 64-bit library and updated the Database. But now EVERY computer on the network must use the 64-bit Reader DC. To expand on the response from Test_Screen_Name , there are indeed other reasons why a 64-bit version of Reader and Acrobat would be desirable.For example, there are currently issues with regards to various PDF file manipulation operations in Acrobat involving very large and complex PDF files in which Acrobat runs out of memory space in the its Windows version (32-bit) that don't occur in the Quick solutions: Repair the current program installation using Add/Remove Programs in the Control Panel.

Once this rather hefty download is done you will need to set a 32 bit prefix for wine to use, necessary for the Adobe Acrobat to work properly. (2) More important, if you are currently using any third party plug-ins to Acrobat on Windows, until those plug-in developers provide 64-bit versions of their plug-ins, don't migrate to 64-bit Acrobat. Good luck! PS: I am successfully using the 64-bit version on all my Windows 10 systems. Later I noticed that I had links to both the 32 bit and 64 bit versions in Public Desktop and in my Start Programs list. I am happy enough to continue to use the 64 bit version but would like to remove the 32 bit one. However, the list of programs in Control Panel lists only the 64 bit version. 1VgWe2m.
