1. Determining Your Computer’s Physical Address (MAC address)
Your computer’s Physical Address, also known as “MAC address” or “Ethernet address” can be determined by using the command prompt.
Determine Windows Physical Address Automatically:
Alternatively, use the program CSG-HostID.exe to automatically determine your physical address.
2. Multiple Physical Addresses (MAC Addresses)
If you have several network cards you will also have several physical (MAC) addresses. If you use the “getmac/v” or “ipconfig -all” command, you computer will these addresses. In order to determine which is the correct address for MEDUSA4 Personal licensing, please use the physical address of your local area conn.
For a manual request of the license file, the physical address of the network adapter which is integrated into the computer (no USB adapter) and always active should be selected.
3. Difference between the freeware M44 Personal of the commercial software M4 DRAFTING
M4 Personal offers most of the functionality of the professional M4 version. The following tools are available:
- 2D Drafting (Basic)
- 2D Symbols, creation and und editing
- 2D Parametric Symbols, creation and und editing
- Smart Drafting
- 3D Drafting (Basic)
- Sheet Metal Design
- Import of AutoCAD® DXF/DWG files (Export in CSG eSERVICES)
- Raster files, loading and modifying
M4 Personal is delivered with the documentation of the full version. Due to the limited range of functions, some tools are not available.
M4 Personal has its own license file format. License servers are not supported. When you start M4 Personal for the first time, you have to apply for a license, you will then receive a free license file.
The internal format of M4 Personal drawing files (*.she) and model files (*.mod) is different from the format of the professional version.
The commercial use of plots, PDF files, etc. created with M4 Personal is not allowed, for this reason a watermark is added to each plot.
To use drawings created with M4 Personalcommercially, CAD Schroer provides various conversion services in the CSG eSERVICES:
- Plotting drawings in large formats (A0, A1, A2)
- Converting drawings to PDF or DXF format
- Converting drawings to SHE format of the MEDUSA4 professional version
- Converting models to STL format
Registration in the CSG eSERVICES is free of charge, the plot and conversion services will be charged.
4. Replace license manually
Open a Windows Explorer window and change to the directory \medsys\med\license. You will find your license here with the file name csglmd.lic . If you want to update your new license, rename the new license to csglmd.lic and copy it into the named directory. Overwrite the existing license or rename it before copying.
5. Annual update of license and software
Each M4 PERSONAL license is valid for one year. After that, the license can simply be renewed for another year in the software.
We limit the license usage for several reasons. We publish a new version of M4 PERSONAL almost every year. The license update allows users to upgrade to the new version. We also sometimes change the functions to meet the requirements of our users and adjust them using the new licenses.
6. Does the M4 PERSONAL license cost me anything?
The M4 PERSONAL software as well as the M4 PERSONAL license are completely free of charge and can be downloaded via the CAD Schroer website https://www.cad-schroer.com/products/m4-personal/ or via the eSERVICES portal https://eservice.cad-schroer.com/com/. Licenses are valid for 12 months and can be extended free of charge.
Only the use of designs for commercial purposes incurs a conversion charge. Read more about our Pay per Result principle in this article:

7. Applying for a license
M4 PERSONAL can only be used on PCs with a correctly installed network card.
If you enter the command ipconfig /all or < installation directory >\medsys\med\license\lmutil lmhostid and your machine returns the results 00-00-00-00-00-00 or FF-FF-FF-FF-FF-FF, then this means that your computer does not have a network card installed, or that the card was not properly installed.
A Host ID in the format of 00-53-45-00-00-00 is also invalid, as it is not the physical address of your network card, and M4 PERSONAL will not run in this environment.
8. Update to a new M4 PERSONAL Version
If you want to use the newest version of M4 PERSONAL you need to download the current version and update the license. The old licensekey wont work with the newest version of M4 PERSONAL.
9. What’s a Physical Address (MAC Address)?
A MAC address (Media Access Control Adress, also known as Ethernet ID or Physical Address for Microsoft) is your network adaptor’s unique hardware address, which identifies your machine on a network.
It merely refers to your network adaptor and does not contain any personal information. We need this address to create your M4 PERSONAL license file, which will only run on your machine, preventing illegal copying and misuse of the software.
To find out your MAC address, open a command line and type: “getmac/v” or “ipconfig -all”
10. No license received
1. You do not have an active Internet connection or your firewall is blocking the contact to the license server. Then M4 PERSONAL cannot automatically obtain a license from the CAD Schroer servers.
In this case, use the online form to request a license: https://www.cad-schroer.com/tech-support/medusa4-personal-license/
Fill out the form and download the license to your PC. Select the license file in the licensing dialog.
2. You do not have an active network card and the licensing mechanism cannot identify a valid physical address (MAC address). In this case, activate your network card and restart M4 PERSONAL.
11. Renew Existing License
Your M4 PERSONAL license is valid for 12 months. When it’s expired, simply renew it in the software or visit https://www.cad-schroer.com/tech-support/medusa4-personal-license/ to renew your license for another 12 months.
