Cadworx Splm Error 7502

The CADWorx SPLM Error 7502 occurs when the software cannot read data from the SmartPlant License Manager (SPLM) server. To resolve this, you must ensure that SPLM is properly installed and configured to connect to your license server before starting CADWorx.  Recommended Troubleshooting Steps 

Configure SPLM: Open the SmartPlant License Manager on your local machine and verify that it is pointed to the correct server IP address or hostname.

Verify Installation: Ensure SPLM was installed prior to the CADWorx installation, as the software requires an established license path to initialize.

Check Server Connection: Ensure your computer has a stable network connection to the license server and that firewall settings are not blocking communication.

Restart CADWorx: Once the connection is confirmed in the SPLM utility, restart CADWorx to clear the error.  Official Resources

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 cadworx splm 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. The CADWorx SPLM Error 7502 occurs when the

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

Title: Technical Analysis and Resolution of CADWorx SPLM Error 7502: A Comprehensive Guide to License Configuration Management Open Services

Abstract

This paper provides a technical examination of CADWorx SPLM (SmartPlant License Manager) Error 7502. This error is a common operational barrier in industrial design environments utilizing Hexagon’s CADWorx Plant Design Suite. It typically indicates a failure in the communication handshake between the client workstation and the SPLM license server. This document analyzes the root causes, dissects the underlying architecture of the SPLM communication protocol, and provides a step-by-step remediation strategy for system administrators and CAD managers.

1. Restart the SPLEM Service

• Open Services.msc
• Locate SPLEM License Server or Sentinel RMS License Manager
• Restart the service. If it’s not running, start it manually.

Common Causes and Evidence

1. Network connectivity problems

   • Symptoms: other network services work but CADWorx cannot contact license server; timeouts; intermittent success.
   • Evidence: ping/traceroute failures to license server hostname or IP; error logs showing connection refused or timed out.

2. License file errors or expiration

   • Symptoms: immediate denial on license request; messages about invalid or missing license.
   • Evidence: license manager logs showing malformed entries or “expired” tags; license file checksum mismatch.

3. Version mismatch

   • Symptoms: client updated to newer CADWorx while license manager still runs older licensing service that lacks support for new feature codes.
   • Evidence: release notes showing licensing protocol changes; vendor advisories.

4. Local configuration / permissions issues

   • Symptoms: client cannot read license-related files or registry keys; service fails to start under account used.
   • Evidence: OS event logs, insufficient-permissions errors, file ACLs preventing read/write.

5. Port or service conflicts

   • Symptoms: license manager cannot bind to required ports; firewall blocks incoming/outgoing connections.
   • Evidence: netstat showing port in use; firewall rules denying traffic on the license manager port.

What is SPLM and Why Does Error 7502 Occur?

Before fixing the error, it is critical to understand what SPLM is. SPLM (Software Protected License Management) is Hexagon’s (formerly Intergraph) licensing system used by CADWorx, CAESAR II, and PV Elite. Unlike older hard-dongle systems, SPLM can manage network floating licenses or local node-locked licenses.

Error 7502 is a connectivity or communication error. In plain English, your CADWorx installation is trying to talk to the license server (or local license file), but the handshake is failing.

The primary causes of a 7502 error fall into four categories:

1. Network Disruption: Your PC cannot see the server hosting the SPLM license.
2. Service Failure: The SPLM License Server service is not running.
3. Firewall/Antivirus Blockade: Security software is intercepting the communication port (usually port 2575 or a dynamic range).
4. Corrupted Local Trust: The local TrustedStorage.bin file is damaged.

Step 1: Perform the "Ping Test" (Network Users Only)

If you are using a network license, your computer must "see" the server by its hostname or IP address.

1. Open Command Prompt as Administrator (Type cmd in Windows search, right-click, Run as Admin).
2. Type: ping [YourLicenseServerName] (e.g., ping CADServer01).
3. Result: If you get Request timed out, your network path is broken. Check your LAN/VPN connection.
4. Alternative Test: ping [ServerIPAddress] (e.g., ping 192.168.1.100). If IP works but name fails, you have a DNS or HOSTS file issue.
