When you try downloading the product, you would come across 32-bit and 64-bit options available for download. Here’s the difference between a 32-bit and a 64-bit application:

A system comprises three layers: the processor, the operating system and the application. To run either a 64-bit OS or 32-bit OS, we require support from the lower level, processor. Similarly, to run either a 64-bit or a 32-bit application, we require support from all the lower levels such as OS and processor.

There are two types of processors, namely, 32-bit and 64-bit. These refer to the processor architecture and tell us how much memory can be accessed from the CPU register. For instance, a 32-bit system can access 232 memory addresses, i.e 4 GB of RAM and a 64-bit system can access 264 memory addresses, i.e actually 18 billion GB of RAM. The key difference between these processors is the number of calculations performed per second.

  • In general, 32-bit programs can run on a 64-bit system but 64-bit programs cannot run on a 32-bit system. This is because 64-bit applications include instructions that will not be recognized by a 32-bit processor.
  • A 32-bit OS will run on both 32-bit and 64-bit processors and on the other hand, 64-bit OS will run on only a 64-bit processor. The same can be concluded with 32-bit and 64-bit applications. The main reason behind this is that 64-bit systems are backward compatible with 32-bit systems.

Depending on the architecture of your processor and operating system, download either 32-bit or 64-bit version of the product.
