As long it is not, I cannot install new maps that way.
However, I choose to install the installer update, and it downloads - but it doesn't install, so I come to first step over and over again. How to solve that?
I am using Win7. And I was able to install it freshly without uninstalling the old version first. Now I have both versions :-P (of course I will uninstall old version)
@MapFactor Please fix the reason It could be caused by the 12x version incorrectly updated to 14x. When update for 14x was available, it installed itself without problems at that time, but everything was still stored in the 12x folder, from where now the upgrade to 15x failed.
