you for reaching out on the community and telling us about your issue. I do
apologize for the issue you're having. Did you get this error after installing a recent patch by chance? Lets try to see if we're able to get you up and running with a support article. It has different steps we're able to take to see if we're able to get you back up and running.
Once you get a chance let us know if this helps get the program open. If not we'll see what we can try next.
Thank you for taking the time to come to the Community to post your question, however, this is an older post and less likely to receive an answer.
I would suggest creating a new post for better visibility.
Be sure to include a description of the issue, any error messages as well as the version of Quicken.
The more information you can provide will help the Community to better understand and assist.
