Hi ashtoor,
Welcome to Community! It's important that you're able to access your QuickBooks Desktop account and get back to business as soon as possible. I'd be happy to help!
Although performing a hard reboot on your system shouldn't remove any of your installed programs, you can install your QuickBooks account once you've downloaded it by following this link.
Please don't hesitate to contact us if you require additional assistance. It would be our pleasure to work with you in real time and ensure you're back to business as soon as possible!
