Which is which
- WinRAR, WinZip, CCleaner Professional and Foxit PDF Editor are delivered as keys. Install the app first, then enter the key in its registration or licence screen.
- PDF Expert asks for your Account Email at checkout — the seller upgrades that account, so there is nothing for you to enter.
Always download the app from the vendor's own website. A licence bought here activates the genuine build, not a repack.
