Thanks and welcome aboard to the Community, @qualacct.
When installing multiple QuickBooks Desktop versions on your computer, please make sure these programs are compatible with each other. I recommend visiting the Install multiple QuickBooks Desktop versions on one computer article for more insights about the things you should consider.
For importing web connect files, please also note there's only one process available at this time. It would be by opening the QBO file within the program to download bank transactions.
I can see how this ability is beneficial to your business. Right now, opening the downloaded file directly from your computer is currently unavailable.
For the time being, I suggest visiting our blog and sign up to our Newsletter. This way, you’ll receive email updates about changes in the product.
