New to infopath ...error using published form

[jj]

I have a simple form and published it on a shared folder. However I get this
message everytime I try to use the form.

Form template: \\server\sharedfolder\test1.xsn

The form must be registered by a setup program before it can be opened.

The following form template is not registered:
urnscemas-microsoft-comffice:infopath:test1: -dataformsolution



Any help is appreciated

Thanks
