I have a product key for PagePlus X5. However, I need to reload as I am changing PCs and I need the download of the full X5 version.
Yes, this is the original version, but it's not the X5 one. Also, the latest version of Serif PagePlus Starter Edition is X9 and it can be acquired from its official website.
If you need the X5 version, then simply access the Legacy menu on the same page and choose the product you need. You'll find additional information on the page you visit.
