Thank you for the details, @Miha347. I am happy to guide you in installing your QuickBooks on a new computer.

Before we begin, would you mind telling me more about it? Like, have you encountered any errors when trying to install QuickBooks on your second computer? Additional details will help me check the cause of this. A screenshot would be a great help too.

To move your QuickBooks to your second computer, you'll want to install it on your computer and restore a backup copy of your company file. Ensure that it meets the system requirements. See this article, System Requirements for QuickBooks Desktop 2022.

First, download QuickBooks Desktop (QBDT) from the website. Here's how:

1. Open the file QuickBooks.exe.
2. Follow the on-screen instructions. Accept the software license agreement and then select Next.
3. Enter your product and license numbers. Then select Next.

Then, proceed with installing QuickBooks. For your guide, check out this link: Install QuickBooks Desktop.

Once completed, you can restore your files to the newly installed QBDT.

1. Go to the File menu, then tap Open or Restore Company.
2. Choose Restore a backup copy and then Next.
3. Select Local Backup and then Next.
4. Browse your computer for your backup company file. It should look like this: [Your company name].qbb.
5. Select a folder to decide where to save your restored company file. Then select Open.
6. When you're ready, select Save.

If you run into problems restoring your backup file, here's how to fix them.
