No. National Instruments (NI) has never released an official portable version of Multisim. The software is designed as an enterprise-grade EDA tool that relies on background services, license managers (NI License Manager), and deep Windows integration. Official distribution is strictly through standard installers.

Verdict: 3.5/5 Stars

Multisim Portable is an unofficial, "unauthorized" version of the industry-standard NI Multisim circuit simulation software. While the official Multisim requires a hefty installation, license activation, and ties to National Instruments hardware, the "Portable" version promises the full power of SPICE simulation in a standalone executable.

For students, hobbyists, and engineers who need to access schematics on different computers without administrative privileges, it is a lifeline. However, it comes with significant legal, ethical, and stability caveats that cannot be ignored.

Instead of making Multisim portable, make the entire operating system portable.
