1. M4 PERSONAL Installation Guide

We deliver M4 PERSONAL always with an installation guide. You can download it as a PDF document in the download area:
https://www.cad-schroer.com/fileadmin/Download/datasheet/MEDUSA4-PERSONAL-v7-0-Installation-Guide.pdf

2. Supported languages

M4 PERSONAL can be installed in English, German, French or Italian.

The documentation and online help are available from CAD Schroer in German and English.

3. Installation directory on Windows 10

Choose for the M4 PERSONAL installation folder a path name which does not contains blank spaces or special characters, this is why the default installation path cannot be (C:\Program Files).

4. Installation won’t start, aborted after extraction or is taking a long time

The installation can be aborted by several reasons.

1. The installation of M4 PERSONAL is executed by a user without administrator rights

If this is the case, there may be problems during installation. In this case, cancel the installation and ask the administrator to run the installation again.

2. The temporary directory does not exist or is named incorrectly

Make sure that the directory C:\temp exists and is writable.

If the extraction process stops after reaching 100 percent and the DOS error message « The system cannot find the specified path » appears, check whether the temporary area has a DOS-compliant name. Please check under « Start > Settings > Control Panel > System » in the tab « Advanced » on the item « Environment Variables » whether the variables « TMP » or « TEMP » do not contain special characters.

3. Blocking by the Windows firewall or the virus scanner

Unfortunately, some virus scanners cause problems when downloading, installing or running M4 PERSONAL, because the latest virus scanners do not know some M4 PERSONAL files. As these are unknown, their status is considered potentially dangerous and the virus scanner interrupts the download / installation / execution.

We assure you that M4 PERSONAL does not contain any viruses or trojans!

Please let us know which M4 PERSONAL files are classified as dangerous and which virus scanner you are using. We can then contact the software vendor so that this incorrect classification can be corrected at the next update of your virus scanner.

You can configure the Windows firewall under Control Panel > Windows firewall > Exceptions (for DRAFT.EXE and MX.EXE) or configure the firewall in such a way that it does not prevent the execution in principle, but requests its execution.

4. Broser path configured incorrectly

If you specify Firefox as browser and the path there is « C:\Programs\Mozilla Firefox\firefox.exe »
is enclosed (quoted) with  » then errors can occur. Please always use paths without  » …  » must be specified.

5. Windows security warning during installation

When executing the M4 PERSONAL installation file, Windows may display the security warning “Do you want to run or save this file?”

This dialog appears automatically because the M4 PERSONAL installation file does not contain a Microsoft signature. Click on “Run” to start the installation process.

6. Supported operating systems and hardware

Information about the currently supported operating systems and hardware can be found under:

Open the Command Prompt:
Windows 7: To get to the Command Prompt click Start>All Programs>Accessories>Command Prompt.
Windows 8 and Windows 10: On the desktop press the Windows key and the X (Windows+X) key together. Choose Command Prompt from the Power User Menu.

Determine Windows Physical Address:
At the prompt type « getmac /v » or « ipconfig /all ».

Video Tutorial

For Your Information: You must provide a valid physical address in order for the software to install and run on your machine. We only use this address to issue a software license file (keyfile), which allows the downloaded software to work and is locked to your specific machine.

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/m4personal 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:
https://www.cad-schroer.com/news/articles/the-pay-per-result-principle/

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/medusa4-pl-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.

1. Remove watermark from printed page

Each M4 PERSONAL printout includes a watermark that informs the users that for commercial use, drawings must be converted in the CSG eSERVICES.

The conversion of the drawing into PDF, DXF or DWG format can also be done via the dialogue « File > eSERVICES conversion ». This requires the purchase of a conversion contingent in the CSG eSERVICES.

The conversion can also be done directly in the CSG eSERVICES.

There is no watermark in the converted files, which means that they can also be used commercially.

2. Print in colour from M4 PERSONAL

Both plotter drivers available in M4 PERSONAL are set up to print in monochrome by default. You can change one of these to allow you to do colour printing.

To do so, select « File > Options > Administrator » and enter the password “admin”. Then select « File > Options > Plotter configuration ».

The dialog presented lists all available plotter drivers. Select the “qtplot” plotter driver and click the “Edit Description” button.

In the file presented, change the text so that you comment out (add a “–“ to the line defining) the black and white printing options, and remove the comment marks from the colour printing options, then save the file:

6. Using other QT Libraries

QT libraries are used to define the user interface in M4 PERSONAL. The libraries that should be used by the software are located in the directory « <installation directory>/medsys/med/share/ ». If you receive an error message relating to a QT DLL when starting the system, then you probably have other QT DLLs in the SYSTEM32 directory. You will need to redefine the PATH environment variable to pick up the /medsys/med/share/ folder before the SYSTEM32 directory.

7. Change background colour of the sheet

To change the background colour of your M4 PERSONAL sheet you need to switch to Administrator under « File > Options > Administrator » and entering the password “admin“. Change the background colour in the menu under « File > Options > Administrator ».
