Adobe will soon release 64-bit Acrobat on Windows 10. The 64-bit Acrobat application will have all the obvious advantages:
Currently, third-party plug-ins developed using Acrobat SDK work fine on the 32-bit Acrobat application on Windows. To make those plug-ins work on the 64-bit Acrobat, the plug-ins must be upgraded to 64-bit.
The users should contact the third-party vendor to get the plug-in upgraded to 64-bit.
If you need help with upgrading the plug-ins to 64-bit, contact Adobe on firstname.lastname@example.org.
