First, a quick definition: SPLEM stands for Software Protected License Encryption Manager—the license management system used by Hexagon’s CADWorx suite.
Error 7502 typically translates to: “The license server cannot be reached, or the license file is invalid/missing.”
In plain English: CADWorx wants to check your license, but something is blocking the handshake.
For engineers, designers, and piping professionals, CADWorx is an indispensable tool for plant design. However, like any sophisticated software tethered to a license manager, it is vulnerable to validation errors. Among the most vexing is the CADWorx SPLM Error 7502.
If you have been staring at a dialog box that reads “SPLM Error 7502: Cannot connect to license server” or “Error checking out license (7502)”, you know the frustration of being locked out of your project mid-deadline.
This article dives deep into the anatomy of Error 7502. We will cover what the error means, why it happens specifically within the SPLM (Software Protected License Management) ecosystem, and a step-by-step roadmap to diagnose and resolve the issue permanently.
This is a very common cause for Error 7502. SPLM communicates primarily via UDP port 7447.

Conclusion
Cadworx SPLM Error 7502 is fundamentally a communication barrier. By systematically checking the service status, network connectivity, firewall ports, and license file validity, you can usually restore functionality relatively quickly. If the issue persists after following these steps, contacting Hexagon Support with your license file and server details is the recommended next course of action.
CADWorx SPLM Error 7502 indicates that the software could not read data from the SmartPlant License Manager (SPLM) server. This communication failure typically occurs because SPLM is either not properly configured on the local machine or cannot reach the licensing server. Core Cause
The error triggers when CADWorx attempts to validate its license against an SPLM based system and fails to establish a connection. This is common in older applications still using SPLM, which has largely been predated by Intergraph Smart Licensing (ISL). Immediate Solutions
Configure SPLM Connection: Ensure that the local computer is correctly configured to point to the license server using the SPLM utility.
Verify Service Order: SPLM must be installed and fully set up before launching CADWorx so that a license can be obtained at startup.
Network Check: Confirm connectivity to the server and ensure that firewall or proxy settings are not blocking the licensing ports.
Check Hardware Locks: If you are using a physical lock, ensure it is connected and recognized, as error 7502 often occurs alongside hardware lock errors. Modern Migration
Hexagon (formerly Intergraph) has ceased generating new license keys for SPLM as of December 31, 2024. If your organization is still using SPLM, the long-term resolution is to upgrade to the Intergraph Smart Licensing (ISL) Client.
Repair Installation: If the client software is installed but failing, use the Repair Client Software tool in the Windows Control Panel.
Time Synchronization: Ensure your local computer's date and time are synced with the license server, as a mismatch can cause licensing failures.
If these steps do not resolve the issue, you should Contact Hexagon Technical Support with the specific error number and any accompanying description from the error log. If you'd like, I can help you: Find the latest ISL setup guides Troubleshoot specific network ports for licensing

Troubleshooting CADWorx SPLM Error 7502: Causes and Solutions
CADWorx SPLM Error 7502 is a licensing error that indicates the software could not read data from the SmartPlant License Manager (SPLM) server. This error prevents CADWorx from launching because it cannot verify a valid license from the designated server. Core Cause of Error 7502
The primary reason for this error is a communication failure between the client machine (where CADWorx is installed) and the SPLM server. This can happen if: SPLM is not properly configured on the local computer.
The SPLM server is unreachable due to network or firewall issues.
The licensing software was not installed or set up prior to running CADWorx. Step-by-Step Solutions to Fix Error 7502 1. Configure the SPLM Client
If SPLM licensing is available, you must ensure the local machine is pointed toward the correct license server.
Open the SmartPlant License Manager utility on the client computer.
Select Configure and Test > Select License Machine for Client.
Enter the correct Node Name of your SPLM server and click OK. 2. Verify Firewall Exceptions
Often, a firewall blocks the communication between the client and the server. You must allow the SPLM executable through the Windows Firewall.
Go to Control Panel > Windows Firewall > Allow a program or feature through Windows Firewall. Click Change settings and then Allow another program.
Browse to the pdlice.exe file (default path: C:\win32app\ingr\splm\bin) and add it to the exception list. 3. Check for Service Disruptions
If the server is configured correctly and the firewall is open, the license service itself might be down.
Ensure the Intergraph Smart Licensing service is running on the server.
Verify that licenses have not expired or reached their maximum concurrent user limit. Modern Alternatives: Upgrading to Smart Licensing
Hexagon has transitioned away from the legacy SPLM system. As of December 31, 2024, Hexagon no longer generates license keys for the older SmartPlant License Manager.
If you frequently encounter Error 7502 on older applications, Hexagon recommends upgrading to Intergraph Smart Licensing (ISL). ISL is the next-generation cloud-based system that replaces the need for local SPLM servers and hardware locks. Summary of Quick Fixes Configure SPLM Link the client computer to the server Node Name. Add Firewall Rule Allow pdlice.exe through the firewall. Restart Service Ensure the license manager service is active on the server. Upgrade to ISL
Move to the supported Smart Licensing platform for long-term stability.
If these steps do not resolve the issue, you should contact Hexagon PPM Technical Support and provide the specific error number (7502) along with a description of your network environment. Intergraph Smart Licensing - Version 14.3 - Help - Hexagon
CADWorx SPLM Error 7502 is a common licensing issue that occurs when the software is unable to communicate with the SmartPlant License Manager (SPLM) server. This error typically stops your workflow by preventing CADWorx modules from launching, often displaying the message: "Could not read data from SPLM server". First, a quick definition: SPLEM stands for Software
The guide below provides a comprehensive walkthrough to diagnose and fix this error. Understanding Error 7502
At its core, Error 7502 signifies a broken connection between your local CADWorx installation and the license server. This can happen if:
The SPLM software is not installed or configured on the client machine.
Network issues are preventing the client from "seeing" the license server.
Firewall settings are blocking the specific communication ports used by Intergraph/Hexagon software.
You are using an older version of SPLM that has been deprecated in favour of Intergraph Smart Licensing (ISL). Step-by-Step Solutions 1. Verify SPLM Client Configuration
The most frequent cause is that the local machine doesn't know where to look for the license.
Open the License Manager: Go to Start > Programs > CADWorx > License Manager.
Check Connection: Ensure the computer is configured to point to the correct SPLM server IP address or hostname.
Restart CADWorx: After making changes, fully restart the application to trigger a fresh license check. 2. Check Firewall and Network Access
If the configuration is correct but the error persists, your network may be blocking the "handshake" between the client and server.
Add Firewall Exceptions: Ensure pdlice.exe (usually located in C:\win32app\ingr\splm\bin) is allowed through the Windows Firewall.
Test Connectivity: Open a command prompt and try to ping the license server’s IP address. If the ping fails, you have a general network connectivity issue that must be resolved by your IT department. 3. Address Legacy Software Conflicts
Intergraph (Hexagon) has transitioned away from the traditional SPLM system.
Upgrade to Smart Licensing: As of December 31, 2024, Hexagon no longer generates new license keys for the old SPLM system. If your organization has migrated, you must install the Intergraph Smart Licensing (ISL) Client instead of the old SPLM client.
Clean Install: If you have both SPLM and ISL installed, they may conflict. It is often recommended to remove the old SPLM before installing the new Smart Licensing system. 4. Advanced Troubleshooting Intergraph Smart Licensing - Version 14.3 - Help - Hexagon
