How to Install and Activate 2PDF

After you install the commercial version of 2PDF with a Serial Number provided after purchase, the program gets activated automatically over the web and is ready to use. 

If the automatic activation doesn't work for some reason, please try activating 2PDF manually.

Trial and commercial version compared

Trial version

You can download the trial version of 2PDF for free to try out the program for your needs. The trial version of 2PDF is a full-featured version for free testing and evaluation only. Please note that the trial version adds a special "Created by free version of 2PDF" watermark in the corner of every output PDF page.

How to disable the dialog prompt of the trial version

The trial version has an interactive dialog ("Before you start converting process…") with three options to choose from: continue, get the full version, or exit. To make 2PDF start working instantly without waiting for input, you can disable this dialog by adding -options alerts:no string to the command line. For example:

2PDF.exe -src "C:\In\*.*" -dst "C:\Out" -options alerts:no

Commercial version

The commercial version allows you to convert an unlimited number of files with no restrictions, without nag screens or any other limitations. 

Buying 2PDF is a one-time purchase, with no additional fees. After successful activation, you can use the program as long as needed without any additional payments.

Minor updates (for example, version 1.0 > 1.1) are free for all paid users until the next major update. Major updates (for example, version 1.0 > 2.0) are available for our registered customers with a 50% discount.

This version needs activation. Activation of the commercial version is needed to verify that a genuine license copy of the program is used. Besides, verifying the authenticity of the license key ensures that a valid number of installations is not exceeded.

1 License Key = 1 Windows User Account

If you buy a 1-user commercial version – it is valid for one (1) Windows User account on a server. That means you can use one license copy on one server only. In other words, you need to have a single commercial license to be able to install and use 2PDF on one server computer. 

It is recommended that you install and activate 2PDF on the desktop or server where you are going to actually use the program. To install 2PDF for more users, please buy the corresponding number of licenses.

Installation and activation

After getting a commercial version of 2PDF you will receive an email with a download link to the commercial version of the program and a unique Serial Number (license key).

Admin Rights are required

You must have administrator rights to install 2PDF and complete the activation. Please make sure you have sufficient rights or contact your administrator for help. You'll need to be able to confirm the "Do you want to allow this app to make changes to your device?" dialog which appears during installation.

Download the installation file received via email after the purchase, open it, and follow the on-screen instructions to finish installation. During the installation process, you will be prompted to read and accept the End-User License Agreement (EULA), and select the destination folder.

Automatic activation

2PDF will attempt to activate automatically during installation (silently, without any requests to the user). If the activation fails, then 2PDF will repeat activation attempts every time it starts. After successful activation, 2PDF will work without any requests.

Automatic activation may not work on your workstation or server due to several reasons. If it throws an error due to no Internet access, lack of admin rights or any other reason, use the manual activation method below.

How to check the activation status and the Serial Number?

To check activation status of your 2PDF license, run this command:

2PDF.exe -about

Using this command, you will see your Serial Number, too. Alternatively, you can find it at:

What does "2PDF could not be activated: Server returned unknown error" mean?

Most likely, your security system blocked 2PDF's online activation attempt. Try the manual activation method or contact your administrator.

What does "2PDF could not be activated because activation limit for your serial number has been exceeded. Please try to activate again with the help of our web form" error mean?

That means you have already activated 2PDF on a number of Windows User accounts according to purchased license copies and the activation limit has been exceeded. Try manual activation or contact us for assistance.

What does "2PDF could not be activated because the payment notification for your serial number has not been received yet. Please try again in 30 minutes or try to activate 2PDF with the help of our web form." error mean?

Please try activating 2PDF again after a short while (about 30 minutes) using the manual activation method.

How do I migrate my license key to another device? I need help transferring 2PDF to a new PC, since the old one is unavailable (broken, sold, etc.).
