Hi there, @Shiran Madal.

Thanks for coming to the Community for help. It's my pleasure to help you move your QuickBooks Desktop to a new computer. 

When transferring the program to a new computer, you need your product and license information. Then, make sure to uninstall existing QuickBooks first before attempting to reinstall. 

Here's how to install QuickBooks:
1.    On the computer where you want QuickBooks desktop installed, download the installation files or insert the CD.
2.    Download QuickBooks Desktop, then click the QuickBooks executable file installation.
3.    Choose Yes to All, then click Next.
4.    Agree to the Software License Agreement, then select Next.
5.    Enter your License and Product numbers, then select Next.
6.    Then, choose the type of installation for the computer.
7.    Select where you’ll be using QuickBooks.
8.    Click a new install location, then select Install. 
9.    Hit Open QuickBooks to get started!
10.  Activate QuickBooks. 

If you’re moving a single user only QuickBooks, you can use the new Migrator Tool in transferring your program and your files. This is available in QuickBooks 2019 and is being rolled out in phases in older supported versions.

Here’s an article for your reference: Move or reinstall QuickBooks Desktop in another computer.

That should answer your question for today. Let me know if you need anything else, I’ll be here to help. Take care and have a great day!
