Had the same issue for myself. Dont know if its the right solution but I went into the FTP and simply renamed the old directory for woocommerce to “woocommerce-old”.
Then I tried again to install the plugin and it worked. I haven’t launched the website yet but I think that everything is still there since its stored in the db.
Hopefully any skilled yoda can tell you the exact and correct solution but this worked for me.
