TSHV1H and L are the complete TSH installer and patches. The H and L refer to High and Low resolution. You can safely ignore this as ALL modern video cards should use the H version. The L version was made for old video cards with less than 32 MB on board.
Once you install the program, the TSH INSTALLER will be available. It will show a box with various check boxes. Two of those correspond to OBJECTS 1 and Objects2.
Check the boxes, click APPLY and you are good to go.
