How to properly deploy python project that uses pywin32 modules

Question

I recently finished a project for a client that essentially is a scrolling wall calendar. It uses a module called pywebview that uses some pywin32 modules which I don't know how to properly install on the clients computer unless I did it myself. I've been able to find the error in question, but only in regards to py2exe, and I'm reluctant to use py2exe as its my experience that it drastically slows down my programs (I had been trying to use pynsist). If anybody can help, I'd appreciate it. If it helps, the project can be accessed here
