Once you've downloaded the PDF2XL installer onto your computer, you can perform the installation.
This is a fairly simple process and all you need to do is follow the prompts.
Run the installer by double-clicking on it, or right-click and "Install"
Click "Next" on the welcome screen
Place a check in the End-User License Agreement box and click "Next"
Place a User Name and Organization (optional) to register the software to, and click "Next" (this dialog does not exist in version 7.0+)
If you wish to change the Destination Folder where PDF2XL will be installed to, you can click the "Change" button, or simply click "Next" to use the default folder
Choose your Shortcut Options and click "Next"
Once the software has completed its process you can click "Finish"; if you don't want to launch the software right away, remove the check from "Launch PDF2XL"
Now you're ready to activate your software.
