I understand how important accessing the QBO desktop app is and I appreciate all your efforts, @Kyle__D , @WillC2 , @Hawthorne-IS. I recommend contacting our live support team to further check why you’re unable to launch the desktop app, and they can also guide you through the next steps.

Here's how:

1. Go to Help.
2. Select the Search tab, then choose Contact Us.
3. Type in your issue or concern in the field.
4. Hit Continue.
5. Click the Chat or Callback option.

Our live support team is available Monday to Friday, 6 AM–6 PM PT, and Saturday, 6 AM–3 PM PT.
 

In the meantime, I recommend using the QuickBooks Online Desktop app through the web browser as an alternative.

If you'd like to add a QuickBooks Online shortcut to your desktop, refer to this article: Create a desktop shortcut.

We'll be around to help you if you have any other concerns.
