I lost my quickbooks 2015 and 2018 when my computer was cleaned up few days ago , now i want them back on my computer

Hello there, @kquinn1793,

Let's get your QuickBooks 2015 and 2018 back into your computer so you can continue working with your account.

If you're referring to your QuickBooks Desktop accounts, you can download and install the software. Just make sure to have their product and license numbers ready. You need them during the installation process.

Let me guide you through on how to accomplish this:

1. Go to the Download QuickBooks Desktop page.
2. Select your country, product, and version.
3. Click the Search button. 
4. Click Download. 

Once done,  you can now install the software and restore your company file.

Let me know if you have follow-up questions by leaving a comment below. I'd be glad to help whenever you need further assistance.
