Error Message
Activation or deactivation failed. Error code:ERR103.
Cause and Solution
The activation code used cannot activate the currently installed version. This error arises from the wrong version of Foxit PDF Editor has been installed. For example, when a customer uses a registration code for official version to activate on a customized version or an OEM version.
To solve this problem, please uninstall the currently installed Foxit PDF Editor and install the corresponding version that your registration code works for, then try to activate Foxit PDF Editor again.
To find the download link of the allowed version for your activation code, you have the following optional ways:
The first method: search through your e-mail message to see if there is an order email from Foxit Software Incorporated no-reply@email.foxitsoftware.com or orders@foxitone.com, then find the software download link there.
The second method: Find your order information and the download link of your purchased software under your Foxit account on the Foxit website. Click here to learn how to do that.
