Hi there and welcome
You do not need any, just connect the Olympus to your computer.
You will see it appear as a drive when you go to the file manager (you can press the windows key + E to get there)
Then you can copy the recordings directly from there to your computer.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know how you go please.
