MetaQuotes (the developer of MT5) no longer offers a separate 32-bit installer for Windows. The standard MT5 installer automatically detects your operating system (32-bit or 64-bit) and installs the appropriate version. If you run the installer on a 32-bit Windows system, it will install the 32-bit version. On a 64-bit system, it installs the 64-bit version.
Would you like step-by-step instructions for the command-line method, or help finding a broker that still offers 32-bit installers?
