QB Issue Resolution:

I’m so sorry you’re having trouble opening your Simple Start 2010 QuickBooks Desktop file. We’ll first need to:

Install a free 2012 version of QuickBooks desktop for Windows, then it’s really easy to import.
You can download the 2012 version here and use the license and product numbers provided to use it for a limited time (30 days but don’t register it):
License number: 7482 – 8847 – 2621 – 492
Product number: 204 – 992

Once you have this installed, just click on Open and browse to where you have the .QBW file on your computer. Then click on Company, Export Company File to QuickBooks Online, and follow the instructions.
Please let me know of that helps, and thanks for choosing QuickBooks Online!
