PDF Shaper Free

I'm a teacher and my new schoollaptop no longer provides me with administrator rights and so I at a bit of a loss at installing my favourite apps. After a couple of weeks struggling I remembered PortableApps from the time that i kept a USB-stick with the apps that i need to have at hand.
I managed to install PortableApps on my school OneDrive, including a couple of my fav apps.
But unfortunately PDF Shaper is not on the PortableApps list.
I asked the maker of PDF Shaper if they'd be considering releasing a portable version (for PortableApps) and their response was: You can use the Free version as a portable application (a single .exe file). The other versions require registering ActiveX DLLs in the system

So, I've been briefly looking into the guide towards buidling a portableapp, but found it a bit intimidating, particularly the registry part.

Would someone more experienced be able to lean in and create the PortableApps PDF Shaper?
