Surfer 10 and above are available in a 32-bit and 64-bit versions. Surfer utilizes a hybrid installer. Both the 32-bit version and the 64-bit version of Surfer are packaged together. When you install it on the computer, the installation detects the type of operating system you have. If you have a 32-bit operating system, Surfer will automatically install the 32-bit version. If you have a 64-bit operating system, Surfer will default to the 64-bit version but you do have the option to install the 32-bit version instead if you wish.
