Step 4: The Windows Firewall Deep Dive (Port 2575)
SPLM typically uses TCP port 2575. However, some newer versions use random dynamic ports. Error 7502 frequently appears after a Windows security update resets the firewall.
On the License Server:
- Open Windows Defender Firewall with Advanced Security.
- Click Inbound Rules > New Rule > Port.
- Select TCP > Specific local ports: Enter
2575. - Choose Allow the connection.
- Apply to Domain, Private, Public.
- Name it "SPLM Inbound".
On the Client PC:
- You may need to allow outbound traffic on port 2575, though inbound rules on the server are usually sufficient. To be safe, temporarily disable the firewall on the client (for 30 seconds) to test if the 7502 error disappears. If it does, create an Outbound Rule allowing CADWorx.exe and SPLM.exe.
5. Use the SPLM Monitor/Client Configuration
On the client machine, you may need to explicitly define where the license is located.
- Search for SPLM License Setup or Client Setup in the Windows Start Menu under the Cadworx folder.
- Ensure the License Server field is populated correctly.
- Try using the IP Address instead of the Server Name if DNS issues are suspected.
- Ensure the port is specified if required (e.g.,
7447@192.168.1.50).
