Installation troubles

Hello everybody,

I have just downloaded Draftsight and just before the end of the installation process the following message appears: "the installation path specified  is too long" then I have to cancel the installation. See the picture enclosed (in italian).

I'am running windows 7 - 64 bit, home premium service pack 1 -  and trying to install DraftSight for Windows 64bit1,3,4(V1R3.2).

what can I do?

I thank you for your help.

Andrea
