License code installing issues

After succesfully installing the standalone license code, it does not work when later starting the program

The DeskArtes Expert Series programs use the network interface MAC addresses as ID numbers for the license.

The problem appears usually when there is a network adapter with a dynamic MAC address, meaning that the adapter is not always connected to the machine or its MAC address is just changing. If the license is created for that kind of MAC address, the license only works when the MAC address is available on the system.

The solution is to select a more stable MAC address in the list of System ID numbers, shown with the "Help->Licenses: Show ID details" command, and order a license code for that ID. Usually the MAC addresses of the Ethernet controller and the Wireless network adapter on the machine motherboard are most stable.

Installing the standalone license code fails with error message: "Unable to update the license file. You are not allowed to create or overwrite the file"

When a license code is installed with the "Help->Licenses: Install license code" command, the license code is saved into a file under the system ProgramData folder.

If the user account, used for installing the license, does not have write access right to that folder, the installation fails and the error message is shown.

One solution to this is to use a user account with administrative rights to install the license.

In some cases a better way is to install the license code manually to the file using the Windows Notepad program.

  • Start the Windows Notepad program.
  • Copy/paste the license code to the Notepad window.
  • Use Notepad "File Save As" command to save the license into a file
    "dalic.<SystemID>.txt", where the <SystemID> is ID number the license was created for. For example if the ID number is 12b9a5f5ad6b, then the name of the license file is "dalic.12b9a5f5ad6b.txt
  • Copy the license file to the folder
    "C:\ProgramData\DeskArtes\<SoftwareAndVersion>"
    where the <SoftwareAndVersion> is the name and version number of the software. For example the correct path for the 3Data Expert version 11.0 is
    "C:\ProgramData\DeskArtes\3DataExpert11.0"
  • If there are already some license files (the name starting with "dalic.") in the folder, you can delete them first.
