Hi all,

Please download and install the latest APP version first before continuing.

Forum topic with download links (must be logged in) :


If the Trial license hasn't expired yet, you can click on the top left LICENSE button. This will pop-up a new window with your current license details. Just click on the button "enter new license code" of this pop-up window to install a new license.


If your old Trial license is expired and then start APP, you will get the notice that your license no longer is valid.

In the latest APP versions (1.054 and later), the old license file will be automatically removed in that case. So the next time that you start APP, it will ask for new license details. Fill in your new Renter's/Owner's license details and then you're upgraded.

If you still have trouble with upgrading APP to use the Renter or Owner License, please don't hesitate to contact me at

Kind regards,

@nerd Could you explain what your question about the email is? I did edit it as it's a personal email to you. Or is it that you didn't receive the code? If so, please check your junk mail etc. it should have been delivered.
