easyPDF SDK 6.0 and up, like previous versions, supports Win32 platforms. Unlike previous versions, however, it now also supports Win64 running on the x64 chip set. The 32-bit and 64-bit editions of the SDK are separate packages, so be sure to use the correct one for your operating system as they are not interchangeable. Below are some notes to keep in mind when working on each platform.
The 32-bit edition of easyPDF SDK must be used, and the application that utilizes the SDK must also be 32-bit.
Win64 supports both 32-bit and 64-bit processes. However all drivers, including printer drivers, must be 64-bit. Thus, the 64-bit edition of easyPDF SDK must be used.
The application that utilizes the SDK, by contrast, can be either 32-bit or 64-bit. That choice is entirely up to you as the SDK will work either way.
The 32-bit and 64-bit editions of easyPDF SDK offer the same features and share the same API.
There is one notable exception to this:
Bear in mind that easyPDF SDK supports a wide variety of languages and frameworks, and which one you use may affect whether your program runs as native 64-bit or legacy 32-bit under Win64. For instance, VB6 applications will always be 32-bit, .NET applications are platform agnostic and will always run as 64-bit under Win64, and in some cases cross compilers will allow you to toggle between 32-bit and 64-bit binaries.
