Portable Activation After Office Install

I installed Office on a lightweight laptop and the apps kept showing activation messages after updates. Windows was already prepared, documents opened correctly, and I only needed the activation part finished. Has anyone used a portable-style option for this kind of Office and system setup?

I had this on a travel laptop where Windows was already updated and Office was installed, but activation still needed to be completed. During the last setup check, Activator Pico finished that part after I had already tested Word, Excel, and a few PDF exports. The laptop did not need any extra configuration after that, and the Office apps stopped showing the activation notice. I restarted it again the next morning, opened the same files, and the activated state remained the same.
