What is "Portable" SketchUp?

It is the same as "usually" SketchUp is, but does not require standart installation. It very easy if you are often re-install windows OS.

Where did you get it?

It gave me my friend.

Whatever it is, it is not a supported installation.

Why? The way of file system is the same as SketchUp standard installation ones. Other plugins successfully loading into portable version.

I use SU 2015 x64 Portable. First starting SU was correct with plugins. Next start SU appear errors loading cleanup. TT Lib (latest version) had already installed with extension manager but SU says that it not install. Screenshot below. What is it? Why CleanUp is not loading.
