Check for an EXE file in DOWNLOADS folder.
Self-extracting files are usually come in EXE flavour, but may have MSI or ZIP extensions as well.
Or go to START, in search-box type keywords like TV, Tuner, etc. to see what win explorer digs up.
If that fails, plug in your flash drive, go to CMD console, (DOS commands), type
CD\
CLS
dir/a/s/b'find/i "nameyouwant">flashdrive:\foundit.txt
The pipe symbol ' is Shift+\
"nameyouwant" is any text (filename or part of)
flashdrive: is the drive letter, eg F:
