To install and use QBDT on your second computer. Here's how:
1. Go to your new PC and install QuickBooks.
2. Once done, go back to the old one and create a backup copy of your company file.
3. Copy the backup file to your new one using a flash drive or other external device or through a network, if they're connected.
4. Then, restore the backup on the new PC.
