If you want to download Blender installer in the most secured manner, we suggest you visit Stichting Blender Foundation website and download from their official repositories.
If you already have Blender installed on your systems and U3D files are still not opened properly, check if you have the latest version of the software. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. The reason that Blender cannot handle files with U3D may be that the software is outdated. The latest version of Blender should support all file formats that where compatible with older versions of the software.
