Installation troubles on Win Server 2008

Hi all,

I'm trying to install Robohelp 7 on our development server, a Windows 2008 Enterprise.

Everithing seems to be fine, but at the very end it rollback and suggest to repeat the installation.

Below there is the event viewer message: the translated message reports the application is trying to install a .DLL but the (current) protected version cannot be overwritten by the old version.

Anyone have a suggestion?

TIA

Paolo

Prodotto: Adobe RoboHelp 7. L'applicazione ha tentato di installare una versione più recente del file protetto di Windows C:\Windows\SysWOW64\DBNMPNTW.DLL. Per il corretto funzionamento di tale applicazione può essere necessario aggiornare il sistema operativo. Versione pacchetto: 1996.11.1.0, versione file protetto del sistema operativo: 6.0.6000.16386.
