Error message when running installer

Hello,
I’m changing web hosting companies and am trying to use the Duplicator plug in to move a couple of sites.
I’ve created the .daf files, downloaded the installer and then uploaded them onto the new root directory on the new hosting. When I run the installer I get the following error message and am not sure what to do to fix it and make the install run (I don’t know what the ‘Required file’ means)…

Setup Notice:
An error has occurred. In order to load the full installer please resolve the issue below.
Archive not found! The ‘Required File’ below should be present in the ‘Extraction Path’. The archive file name must be the exact name of the archive file placed in the extraction path character for character.

If the file does not have the correct name then rename it to the ‘Required File’ below. When downloading the package files make sure both files are from the same package line in the packages view. If the archive is not finished downloading please wait for it to complete.

If this message continues even with a valid archive file, consider clearing your browsers cache and refreshing, trying another browser or change the browsers URL from http to https or vice versa.

I’d appreciate any help, thank you so much.
