Symptoms

I am trying to install the software. I have previously purchased a license, but I still get watermarks when the software is used. 

Cause

The most likely cause of this issue is that you have installed a more recent version than your serial key allows, or you have not used the appropriate key for your product. 

Note: If you are moving from an old PC to a new one then you should uninstall the software from your old computer before proceeding. 

Resolution

The first step is to determine which product your license covers, and to check that the license key you're using is the correct one. If you still have access to the old installation of the software then you can check the version information in the Help > About window in order to verify you're using the same version in the new installation.

License Key Details

After successfully logging in, you will see a Welcome page that details your license keys. If the key state is active, and you have active maintenance, downloading the current latest version will be free. If the key state is expired, you will notice a renewal discount and may wish to upgrade to the latest version. However, you can still use these keys with the prior versions for which they are still valid. Click the Download button to download older versions of the software. Note that these installers are only available for 90 days after the expiration of maintenance.

If you are using an old license key that is valid for only a previous version, and you do not want to upgrade to the latest version, then please note the following:

1. Maintenance plan expiry date, which is located in your account under the additional information section. You can download the version detailed in your account until 90 days after the date of maintenance expiration. 
   
2. Note that you may have an old style serial key that does not work in newer versions of our products. In this case you will need to upgrade or renew maintenance on your license in order to use the latest versions. For example, below is a PDF-XChange Editor key, with maintenance until Nov 23 2018. This means that it's possible to install PDF-XChange Editor in the latest version available at that date. If your key is in the old style, and consists of five sets of alphanumerical numbers, then you will need to make a purchase in order to use any build past version 5.5 build 316.1.
3. Your license key and the product it covers appear in your account. There you will see the product name, build number and license key:
   
   This key can be used in version 7.0.326.0 or older.
4. Downloading the software: click the green download button beside the license key to download the correct version of the product for that license key.
