As previously mentioned, if you change the extension you can usually extract and add files through Explorer with the what is built into Windows without adding any software. There are occasions however that you may need the add-in software like PkZip for Windows, WinZip, WinRAR, etc. when you're dealing with ZIP archives that use some of the newer compression or encryption modes.

Perhaps there are then other dependencies, but I am using a fairly new laptop where I don't have many things installed.

The test with besici.xlsx did work right away, so if you can run it again and check the error it should be possible to find out what is missing.
