Question :

How do I enter my serial number?

The simplest way to ensure your serial number is entered correctly is to uninstall all you have installed, restart your system - download the latest release from our downloads page and run the installer provided.

Once the installer is nearing completion you will be asked to enter your registration/licensing info - the last entry field is usually the one where your serial number should be copied from your receipt emailed to you at the time of your purchase - and pasted into the entry field.

The most common causes of problems with licensed use are :

Cause 1:

1: You have typed your serial number incorrectly into the entry field.

Resolution 1:

Copy/paste the serial number in to the installer from your receipt - don't type it !

Cause 2:

2: You have downloaded the wrong install file

Resolution 2:

Check the description of the product on your receipt and ensure you uninstall any previously installed product you are not specifically licensed for of a similar name and ensure you download the correct product from our web site download pages.

Cause 3:

3: You have purchased the wrong product mistakenly and do not realize this - for example, often users buy the PDF-XChange Viewer PRO when they intended to buy PDF-XChange Pro. The Viewer PRO is not intended for the creation of New PDF files primarily (e.g. from MS Office/AutoCAD etc) - but for modifying/Manipulating existing PDF files or scanning pages to a new/existing PDF file.

Resolution 3:

You can either login to our site (registered users section) and use the upgrade option to upgrade at a discounted price to the required product if that is logical (e.g. from PDF-XChange Viewer PRO to the full PDF-XChange PRO Bundle) or Contact us for advice.

Cause 4:

You are trying to remove the evaluation watermarks applied to a file created with a demo version once buying a license for the required product.

Resolution 4:

The only way to resolve this is to go back to step one and recreate the file again from the original source material - it is not possible to remove watermarks once added to a file using the demo version.
