Troubleshooting CADWorx SPLM Error 7502: A Quick Guide If you've encountered CADWorx SPLM Error 7502, you're likely staring at a message that says: "Could not read data from SPLM (SmartPlant License Manager) server". This error typically means your CADWorx software is unable to communicate with the licensing server, bringing your plant design workflow to a screeching halt. What Causes Error 7502?
This error is fundamentally a communication failure between your local machine and the SmartPlant License Manager (SPLM). Common triggers include:
Configuration Issues: SPLM is not properly configured on your local computer to point to the server.
Network Barriers: A firewall or proxy is blocking the license request.
Missing Software: CADWorx was started before SPLM was installed or set up. Step-by-Step Fixes 1. Verify SPLM Configuration
The most frequent cause is that the local machine doesn't know where the license server is.
Open the SmartPlant License Manager utility on your machine.
Ensure you have configured the connection to the correct server IP or hostname. Restart CADWorx to see if the connection establishes. 2. Check Your Firewall Settings
Your computer’s security might be blocking the pdlice.exe program, which handles these license requests. Go to Windows Firewall > Allow a program or feature.
Browse for pdlice.exe (usually found in C:\win32app\ingr\splm\bin) and add it to the allowed list.
Ensure the necessary ports for licensing are open on your network. 3. Match Date and Time Settings
Licensing servers are sensitive to time synchronization. If the date or time on your local machine differs significantly from the license server, the connection may fail.
Ensure both your computer and the server are synced to the same time zone and current time. 4. Reinstall/Update SPLM
If the above steps fail, the licensing files may be corrupted or outdated.
Attempt to reinstall the latest version of the SmartPlant License Manager.

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 Before fixing it, let’s diagnose the culprit: Error

you’re likely dealing with a communication breakdown between your workstation and the Intergraph SmartPlant License Manager (SPLM)
Here is a guide to understanding and resolving this error so you can get back to your 3D modeling. What is CADWorx SPLM Error 7502?
Error 7502 is a common "connectivity" or "license seat" issue. Specifically, it often indicates that the SmartPlant License Manager
cannot communicate with the license server or that the machine is unable to "check out" the required license key for CADWorx. Common triggers include: Network Interruption
: Your computer lost its connection to the server hosting the SPLM keys. Server Service Stopped
: The SPLM service on the license server machine has crashed or was manually stopped. Firewall Blocks
: A recent security update or firewall change is blocking the communication ports used by SPLM. Expired Key/Lack of Seats
: All available licenses are currently in use, or the machine’s specific license "seat" has expired. How to Fix It: Step-by-Step 1. Verify the SPLM Service Status Before tweaking your workstation, check the source. Log into your License Server app (services.msc). SmartPlant License Manager
and ensure its status is "Running." If not, right-click and select 2. Check Your Network Connection
Since CADWorx is sensitive to network stability, ensure you have a "pingable" connection to the server. Command Prompt on your workstation. ping [ServerName] ping [ServerIP]
If you get "Request Timed Out," you have a network issue rather than a CADWorx software issue. 3. Test the SPLM Connection Locally SmartPlant License Manager utility on your machine: Display > Key Status
If it returns "Cannot connect to server," your workstation doesn't know where to look. Configure > Select License Machine for Client and re-enter the correct server name. 4. Firewall and Port Configuration
