You need to make sure that your device has a Blu-ray optical drive, otherwise no matter what programmes you have the disc will not read. From all the specifications I can see, the Latitude D630 only has CD/DVD-RW drives, which won't read or play Blu-ray discs.
You could feasibly replace the optical drive with one that reads Blu-ray, but that may end up being more complicated than necessary.
Any optical drive that's compatible with Blu-ray discs will have the Blu-ray logo in front of the disc dock.
There's also no free software that allows for reading of Blu-ray discs, all of them must be purchased.
OR!!!
Start by closing any DVD or burning software, some of these programs may be attempting to use the drive therefore preventing windows from accessing the disc. Test your DVD drive with several discs as the Blu ray disc may have some defects like scratches or damaged. You can also update your optical drive software and the computer BIOS.
