External Hard Drive sharing fiasco

Im dying to use the Media Player to play my files, Im currently using Plex to do so, but its to damn buggy, sometimes it works sometimes it doesnt, so I really want to use the native Media Player, the problem is that all my media files are stored in an external usb hard drive (Iomega 1tb) and my pc doesnt let me share the drive nor the folders inside the drive, im using windows vista home premium in my computer, when I try to share anything from the hard drive it shows me the message “This program will not run / No such interface supported” I already searched the web (iomega support, windows support, etc) and found a lot of suggestions none of them worked form me, so I wonder if someone had the same problem and managed to resolve it or if this is a known issue.


Thank you in advance
