Problem at installing the software!

Hi!
I'm trying to install the software. I've downloaded MapNodInst.zip and unzip them into a new folder. After that I'm runnnig the setup.exe. But an error occurs "Type mismatch-Une erreur d'installation inattendue s'est produite". Why is that?
Where did I go wrong?

Sincerely,
geographer Covasnianu Adrian

I have installed a new version of the installer:
[mapnod.free.fr]
Could you tell me if it works now?
Thanks,
Alain
