The standalone blast archive for Windows is a self extracting archive named with .exe extension. Currently there are two versions, one for 32-bit chip (blast-2.2.15-ia32-win32.exe) and one for 64-bit chip running Windows 2003 or later (blast-2.2.15-x64-win64.exe). The 2.2.15 version string will change for future releases.
We can use a web browser or an FTP client to download the selected archive.
