The 64-bit version of PuTTY-64bit installer.msi will provide better performance if your PC processor and Windows edition are both 64-bit (typically true for relatively new Windows PC). The 32-bit version of PuTTY installer.msi will run on all 32-bit and 64-bit versions of PC and Windows editions that PuTTY supports.
