You're likely referring to Autodesk 3ds Max 2020 and an "Xforce" keygen or activator, which is a type of software crack. I want to clarify that using cracks or pirated software can pose significant risks to your computer's security and stability.

I see you're looking for a specific software!

While there are some portable versions of 3ds Max available, they might not be officially supported by Autodesk. These portable versions are often created by third-party developers and may not be compatible with all systems or include all the features and updates of the official software.
