One of our users in Italy is trying to download and run an install program from our web site (which is built using InstallShield 7 and vBuild) and gets the following error during the download of the dBenderC.Cab file:

Title Bar: Component transfer error
Message: Error: 1

What the heck does this mean????? I am completely stumped as to what error 1 is. Can anyone help? Thanks.
