In NaviPac 3.10 the PC code could include a negative sign which provoked recurring questions.
This has been removed for newer software packages.

Due to this change you can have two different PC codes on the PC, one in the old software and another in the Licence activator.
To activate NaviPac 3.10, ignore the PC Code from the Licence Activator and use the PC code from NaviPac 3.10.

The following describes two scenario's:

Activate NaviPac 3.10 on the local PC

  • Find the PC code in NaviPac 3.10 and note it down.

  • Start the Licence Activator and enter the licence activation key. 
    You can find the Licence Activator also on the EIVA download site (

  • Set a tick mark into the product that you want to activate, in the screenshot below it is NaviPac Pro

  • Click the option Activate on another PC

  • Enter the PC code that you got from NaviPac 3.10, in the screenshot below this is the PC code 1718295942
    Note, a negative sign is part of the PC code. and must be entered too.

  •  Set ta check mark into the tick box Compatible with NaviPac 3.10 or older.

  • Click the button Generate licence file.

  • The option to create and save the softdongle.txt file opens.
    Copy the softdongle.txt to the C:\EIVA folder on the local PC.

  • Start NaviPac 3.10.
    The licence in the softdongle.txt file is used.

Activate NaviPac 3.10 on another PC

  • Same as above in Activate NaviPac 3.10 on the local PC only use the PC code of the remote computer
  • The option Activate on another PC is required. This way the softdongle.txt file can be made, that NaviPac 3.10 can read.
