Understanding QuickBooks Desktop Licensing (Before You Install)
Before you install QuickBooks Desktop on another computer, it’s critical to understand how licenses work.
Can I Install QuickBooks Desktop on Two Computers?
Yes — if your license allows it.

If you’re unsure about your license, this is often why:
- QuickBooks Desktop license not working on another computer
