Did you add the web part to the library or results page you are testing with? Also note in the current release build there is no loading progress and it does take a second for the document preview to generate. So if you wait a second then hover over again it will display (this is fixed in current build on source code tab).

I install it but even if I wait few secondes, I can't see the preview.

It show me an small popup with write inside "undefined" or "red cross and the text URL preview"

Hi I have got the web part installed but it seems very unreliable. Sometimes a thumbnail will display next to the result link, sometimes it won't. It also seems to only display a single thumbnail for powerpoint docs even if there are several powerpoint search results (only one displays the thumbnail). Do you have any suggestions?? Thanks, Neil

Thumbnail Extender for SharePoint
I totally agree with that. It would be wonderful to be used for Excel and PDF file.
