The combination of "32-bit" (old, unsupported architecture), "Portable" (unofficial packaging), and "Adobe Muse" (discontinued software) creates a perfect storm of security risks, instability, and legal ambiguity.
i just wonder about 32bit operating system - Adobe Community Adobe muse 32 bit portable
There is no official "portable" version of Adobe Muse created by Adobe. If not, you can find of Adobe Muse
Adobe still allows download of older versions if you had a Creative Cloud subscription. If not, you can find of Adobe Muse CC 2015 (32-bit) on archive.org (legal as abandonware debate). Install it normally – it will be more stable than any portable repack. Using a cracked portable version violates Adobe’s EULA
While Adobe no longer sells Muse licenses, the software is still copyrighted. Using a cracked portable version violates Adobe’s EULA. For commercial use, this is a liability nightmare.
Use on Linux (32-bit prefix) or Windows 7 32-bit with RAM limit bypass – but performance will be poor.
