In Solid Edge V20, the SELicense.dat file is the critical plain-text file that contains your license increments (features) and server information.
Location: It typically resides in the \Program folder of your Solid Edge installation (e.g., C:\Program Files\Solid Edge V20\Program\).
Contents: It specifies whether you are using a Node-locked license (tied to a specific CID/Machine ID) or a Floating license (pointing to a license server). Transitioning to "New" Licensing (Post-2020)
If you are trying to use V20 alongside newer versions or on newer hardware, Siemens has introduced several changes:
Value-Based Licensing: Modern versions (Solid Edge 2023+) use a "token" system that is highly flexible but incompatible with the old V20 permanent license files.
CID Retirement: Starting with Solid Edge 2020, Siemens retired the older Unique Host ID (CID) method in favor of a web-based activation or a Composite ID.
Coexistence: You can run V20 alongside a newer version (like 2025 or 2026) using the SESetActiveVersion.exe utility found in the SptTools folder of your installation media. This allows you to toggle which version is "active" in the Windows registry. Licensing Options for V20 Today

I have provided a few variations depending on the context you need (Technical Support Ticket, Forum Post, or Knowledge Base Article).
If you are running a floating license, open the file and look for the SERVER line. It should look something like this:
AOMEI Partition Assistant

my_license_server matches the hostname of your current license server machine. If the server was recently replaced or renamed, this line must be updated to the "new" server name.Analysis of Offline Licensing Mechanisms for Legacy CAD Platforms: A Case Study of Solid Edge v20 Using Self-Managed License Dat Files
The search for "solid edge v20 selicensedat new" is understandable. You want:
The Verdict: Only pursue this if you have a specific reason (e.g., running legacy machine tools that require old post-processors, or maintaining a 15-year-old product design). Otherwise, it is a headache of virtual machines, unsupported file formats, and security risks.
The Best Path Forward:
In summary, "selicensedat new" is a ghost from the past. While you can technically achieve a fresh install of v20 with a legally transferred or reinstated perpetual license, the smarter move is to embrace the modern, free Community Edition. It gives you the same Siemens heritage, a valid new license, and no malware – which is what you truly wanted all along.

Purpose: It contains the encoded permissions for specific features (e.g., Part, Assembly, Drafting) and the expiration date.
Activation: You apply the file using the Solid Edge License Utility, which is found in the Start menu under the Solid Edge V20 folder.
Machine Binding: V20 licenses are often bound to a Host ID or a physical dongle. If you have new hardware, the license usually requires a "re-host" through Siemens to match the new hardware's ID. Useful Resources & Documentation

If you are trying to use a newer license (e.g., from Solid Edge 2020 or later) with V20, note that licenses are not backward compatible. Version 2020 (v220) and newer use the Common Licensing Toolkit (CLT), which utilizes a different daemon (ugslmd) and encryption that legacy V20 cannot read.

For Solid Edge V20, the core licensing mechanism revolves around a specific file named SELicense.dat. This file contains the encoded permissions required to run the software, whether you are using a standalone (node-locked) or a floating network license. Understanding SELicense.dat
The SELicense.dat file is a plain-text configuration file that Solid Edge reads at startup to verify your product features and expiration dates. Format: Usually provided as a .dat or .txt file.
Identification: It is often locked to a specific hardware ID, such as a Composite ID (CID) or a hardware dongle.
Purpose: It defines which environments (Part, Assembly, Draft) and add-ons (Simulation, Wire Harness) are accessible. How to Configure a New License
To set up or update your license in Solid Edge V20, follow these steps: In Solid Edge V20, the SELicense
Obtain the File: Download your updated license from the Siemens License Management site or receive it via email from Siemens.

Open the Solid Edge License Utility from the Start Menu (found under the Solid Edge program group). Click Browse and navigate to your new SELicense.dat file.
The utility will automatically copy and link the file so Solid Edge can recognize it upon the next launch.
Floating Licenses: If using a server-managed license, you must also update the license file on the Siemens License Server and ensure the "Server Name" in the file matches your actual server's hostname. Key Features of Solid Edge V20

Execute the Feature: Select a command like Protrusion to extrude the 2D sketch into a 3D solid body. Key Features in Solid Edge V20 Solid Edge V20 offers several tools to refine your designs: The Fix: Ensure my_license_server matches the hostname of
Material Removal: Use Cutout for through-holes or Chamfer and Round (fillet) for edge treatments.
Advanced Geometry: Add structural integrity with the Rib command or create hollow parts using Thin Wall (shell).
Visuals: Use the Part Painter to apply colors to specific features or faces for better visualization.
