PDF2IMG Licensing Configuration and Common Errors
Estimated Reading Time: 4 MinutesPDF2IMG Licensing Configuration and Common Errors
Overview
PDF2IMG functionality requires a valid Datalogics license in order to run successfully. If the product cannot validate the license, users may encounter activation failures, runtime licensing errors, or messages indicating that the system cannot access the licensing server.
This article explains the most common PDF2IMG licensing issues, why they occur, and the recommended steps to resolve them.
======================================================================
Common Causes of PDF2IMG Licensing Problems
======================================================================
Licensing issues typically fall into one of these categories:
• The activation key is invalid, expired, or entered incorrectly.
• The license has already been activated on the maximum number of machines.
• The system cannot connect to the Datalogics licensing server during activation.
• The license file cannot be found or is not readable.
• A license file was copied from another machine, which is not supported.
Each scenario is described in more detail below.
======================================================================
1. Invalid or Unknown Activation Key
======================================================================
Typical error message
"The activation key you supplied is not a valid license key. Please check the key and ensure that you have entered it correctly."
Or
"The activation key you supplied was not found."
Why this happens
This occurs when the activation key is mistyped, incomplete, or does not match the correct product entitlement.
Recommended resolution
• Carefully re enter or paste the license key exactly as provided.
• Confirm that the key is intended for PDF2IMG licensing.
• If the key continues to fail, contact Datalogics Support to verify the activation key.
======================================================================
2. Expired License Key
======================================================================
Typical error message
"The activation key you supplied has expired. Please enter a valid key."
Why this happens
Some licenses are time limited. Once the license term has ended, the activation key can no longer be used.
Recommended resolution
• Request an updated or renewed license key from Datalogics Sales or Support.
======================================================================
3. Key Already Used on Maximum Number of Systems
======================================================================
Typical error message
"The activation key you supplied has already been used to activate the maximum number of licenses."
Why this happens
Certain license keys are limited to a fixed number of machine activations. Once that limit is reached, additional systems cannot be activated.
Recommended resolution
• Confirm whether the license is already in use on other machines.
• If additional activations are required, contact Datalogics Support to discuss resetting activations or increasing the license count.
======================================================================
4. Unable to Connect to Licensing Server
======================================================================
Typical error message
"Unable to connect to http://ap.datalogics.com. Please make sure that this system is able to access the internet and try again."
Why this happens
PDF2IMG licensing requires outbound internet connectivity during activation, and in some cases during periodic license validation. The software must be able to contact the Datalogics licensing service to confirm that the activation key and license status are valid.
This issue is most common in environments with:
• Restricted outbound internet access.
• Firewall or proxy rules blocking external connections.
• Offline or isolated servers that cannot reach external licensing services.
Recommended resolution
• Confirm that the machine has access to the public internet.
• Ensure firewall or proxy settings allow outbound connectivity to the Datalogics licensing server.
• Retry activation or run the software again once connectivity is available.
• If your environment cannot allow internet access, contact Datalogics Support to discuss alternative licensing options.
======================================================================
5. License File Cannot Be Read or Found
======================================================================
Typical error message
"Can't read license data. No such file or directory."
Why this happens
The software may be unable to locate the license file due to:
• A missing license file.
• An incorrect configuration path.
• Environment variables pointing to an invalid location.
Recommended resolution
• Confirm that the license file exists on the system.
• Verify that licensing environment variables are correctly configured.
• Remove outdated or incorrect license path settings and retry activation.
======================================================================
6. License File Copied to Another Machine
======================================================================
Why this happens
Datalogics licenses are node locked, meaning they are tied to the specific machine where activation occurred. Copying a license file from one system to another is not supported and will cause licensing failures.
Recommended resolution
• Activate the software separately on each licensed machine.
• Do not copy license files between servers or virtual machines.
• If you need to move an installation to new hardware, contact Datalogics Support for assistance.
======================================================================
Summary
======================================================================
Most PDF2IMG licensing problems are caused by:
• Invalid or expired activation keys.
• Activation limits being reached.
• Network restrictions preventing license validation.
• Missing or misconfigured license files.
• Attempting to reuse a license file on another machine.
======================================================================
When to Contact Support
======================================================================
If you continue to experience licensing issues after following the steps above, please contact Datalogics Support and provide:
• The full error message displayed.
• Your operating system and environment details.
• Whether the system has outbound internet access.
• The activation key or license identifier, if available.
Support can help confirm entitlement, reset activations, or recommend the correct licensing approach for your deployment.
