Maple 13 License.dat: A Complete Guide for Installation and Troubleshooting


Maple 13 License.dat: A Complete Guide for Installation and Troubleshooting




Maple 13 is a powerful and versatile software for mathematical computation, visualization, and programming. It can help you solve complex problems, create interactive applications, and explore data and concepts. But before you can use Maple 13, you need to activate it with a license file.




maple 13 license.dat



A license file is a text file that contains information about your Maple 13 purchase, such as your purchase code, your license type, and the number of users allowed. The license file is named license.dat and it is saved in the license folder of your Maple 13 installation. The default location of the license folder depends on your operating system:


  • Windows (32-bit Maple and OS, or 64-bit Maple and OS): C:\Program Files\Maple 13\license\license.dat



  • Windows (32-bit Maple and 64-bit OS): C:\Program Files (x86)\Maple 13\license\license.dat



  • Macintosh: /Library/Frameworks/Maple.framework/Versions/13/license/license.dat



  • Linux: /home/$USER/maple13/license/license.dat



The license file is generated during the activation process, which requires an internet connection. You can activate Maple 13 either online or offline, depending on your situation. In this article, we will explain how to activate Maple 13 with a license.dat file and how to troubleshoot some common issues that may arise.


How to Activate Maple 13 with a License.dat File




To activate Maple 13 with a license.dat file, you need to have your purchase code ready. Your purchase code is a 16-digit alphanumeric code that was sent to you in an email or available on the Maple 13 Installation, Activation, and Technical Support card found in the Maple 13 box. You also need to know your license type, which can be either single user or network.


Single User Activation




If you have a single user license, you can activate Maple 13 on one computer only. You do not need to run a license server or connect to one. To activate Maple 13 as a single user, follow these steps:


  • Insert the Maple 13 DVD into your DVD drive or mount the ISO image if you downloaded it.



  • Run the installer and follow the instructions on the screen.



  • When prompted, enter your purchase code and select Single User as your license type.



  • The installer will connect to the Maplesoft activation server and generate a license.dat file for you.



  • The license.dat file will be saved in the license folder of your Maple 13 installation.



  • You can now start using Maple 13 on your computer.



Network Activation




If you have a network license, you can activate Maple 13 on multiple computers that are connected to a network. You need to run a license server on one computer that will serve out the concurrent licenses to the other computers. To activate Maple 13 as a network user, follow these steps:


  • Install the Maple Network Tools on the computer that will act as the license server. You can find the Maple Network Tools on the Maple 13 DVD or download them from https://www.maplesoft.com/support/downloads/network.aspx.



  • Run the activation utility in the Maple Network Tools and enter your purchase code.



  • The activation utility will connect to the Maplesoft activation server and generate a server license file for you. The server license file is named Maple2022.lic and it is saved in the activate folder of your Maple Network Tools installation.



  • Edit the server license file with a text editor and make sure that the hostname and port number match those of your license server.



  • Start the license manager service on your license server by running lmtools.exe in the bin.win32.x86_64 folder of your Maple Network Tools installation.



  • Install Maple 13 on each client computer that will use Maple 13 over the network.



  • When prompted, enter your purchase code and select Network as your license type.



  • The installer will generate a client license file for you. The client license file is also named license.dat and it is saved in the license folder of your Maple 13 installation.



  • Edit the client license file with a text editor and make sure that the hostname and port number match those of your license server.



  • You can now start using Maple 13 on any client computer that connects to the license server.



How to Troubleshoot Maple 13 License.dat Issues




Sometimes, you may encounter some errors or issues with your Maple 13 license.dat file or your license server. These errors may prevent you from using Maple 13 or cause Maple 13 to run slowly or crash. In this section, we will explain some common errors and how to fix them.


Invalid or Missing License File




This error indicates that there is a problem either with the Maple 13 license.dat file or with the license server that distributes licenses. The error message may vary depending on the exact cause and situation. Some possible causes are:


  • The license.dat file is corrupted, deleted, moved, or renamed.



  • The license.dat file is not in the correct location or has the wrong permissions.



  • The license.dat file does not match your purchase code, license type, or number of users.



  • The license server is down, not reachable, or not configured properly.



  • The license server has run out of available licenses.



To fix this error, you need to check the following:


  • Make sure that the license.dat file is valid and exists in the correct location. You can verify the validity of the license.dat file by opening it with a text editor and checking that it contains your purchase code and other information. You can also try to generate a new license.dat file by running the activation utility again.



  • Make sure that the license.dat file has the right permissions and is readable by Maple 13. You may need to change the ownership or access rights of the file depending on your operating system and security settings.



  • Make sure that the license.dat file matches your license type and number of users. If you have a single user license, you can only use Maple 13 on one computer. If you have a network license, you need to connect to a license server that has enough licenses for all the users. You can check the number of licenses by opening the server license file (Maple2022.lic) with a text editor.



  • Make sure that the license server is running and reachable by Maple 13. You can check the status of the license server by running lmtools.exe in the bin.win32.x86_64 folder of your Maple Network Tools installation. You can also try to ping the license server from a command prompt or terminal window.



  • Make sure that the hostname and port number in the license.dat file match those of the license server. You can edit the license.dat file with a text editor and change the hostname and port number if needed. The default port number for the license server is 27000, but you can use a different port if you specify it in the server license file (Maple2022.lic).



If none of these steps solve the problem, you can contact Maplesoft technical support for further assistance.


System Clock Has Been Set Back




This error indicates that your system clock has been changed to an earlier date or time than when you activated Maple 13. This may cause Maple 13 to think that your license has expired or is invalid. Some possible causes are:


  • You manually changed your system clock for some reason.



  • Your system clock was automatically adjusted by daylight saving time or a network time server.



  • Your system clock battery is low or faulty and causes your system clock to lose time.



To fix this error, you need to do one of the following:


  • Restore your system clock to its original date and time when you activated Maple 13.



  • Re-activate Maple 13 with your purchase code and generate a new license.dat file.



  • Contact Maplesoft technical support for further assistance.



No Such Feature Exists




This error indicates that Maple 13 cannot find the license feature that matches your license type or version. This may happen when you are using a network license and the license server is not configured properly or is running an older version of the Maple Network Tools. Some possible causes are:


  • The license server is using an older version of the Maple Network Tools that does not support Maple 13. You need to install the Maple Network Tools for Maple 13 on the license server and activate it with your purchase code.



  • The license server has not been configured with the Maple 13 server license file (Maple2022.lic). You need to run the activation utility in the Maple Network Tools and enter your purchase code to generate the server license file. You also need to edit the server license file with a text editor and make sure that the hostname and port number match those of your license server.



  • The license server has not been restarted after the service was reconfigured with the Maple 13 server license file. You need to stop and start the license manager service on your license server by running lmtools.exe in the bin.win32.x86_64 folder of your Maple Network Tools installation.



  • The license server is running multiple services for different versions of Maple, and the older service is overriding the current service. You only need one service for Maple 13, as it includes support for the previous two versions of Maple. You need to shut down any services for older versions of Maple on your license server.



  • The license server is using a host-based or user-based license, and the corresponding options file is missing or not set up properly. You need to create or edit an options file with a text editor and specify the hostnames or usernames that are allowed to use Maple 13. You also need to reference the options file in the server license file (Maple2022.lic).



To fix this error, you need to check and update your license server settings and files according to your license type and number of users. You can also contact Maplesoft technical support for further assistance.
