On older versions of Windows, you may need to run the installer manually. On Windows 10, the Edge browser offers to run the installer when the download is complete. If you don't know or don't care, it is always safe to use the 32-bit version ( putty-installer.msi). Many high-end computers sold several years before that. Almost any computer bought after 2015 has a 64-bit processor, except for the very cheapest ones. If you have a 64-bit computer, it is recommended that you install the 64-bit version putty-64bit-installer.msi.

If you need to use an external DLL for GSSAPI authentication, that DLL may only be available in a 32-bit or 64-bit form, and that will dictate the version of PuTTY you need to use. It will run somewhat faster (in particular, the cryptography will be faster, especially during link setup), but it will consume slightly more memory. The 64-bit version (first released in 0.68) will only run if you have a 64-bit processor and a 64-bit edition of Windows (both of these things are likely to be true of any recent Windows PC). PuTTY doesn't require to run as a 64-bit application to work well, and having a 32-bit PuTTY on a 64-bit system isn't likely to cause you any trouble. It will run perfectly well on all processors and on all versions of Windows that PuTTY supports. If you're not sure, the 32-bit version is generally the safe option.
