Hello there, Cessnakid.
Let me guide you through the process of reinstalling QuickBooks Desktop on your new PC and ensure everything runs smoothly on your computer.
You can visit our website to download the QuickBooks Desktop (QBDT) installer. Then, verify that the version you are using is compatible with Windows 11. Please note that if you are using an older or discontinued version, we cannot guarantee a successful installation due to incompatibility issues, and the activation code can no longer be generated online.
After verifying, run the file and follow the on-screen instructions to complete the installation and activation process. Once installed, restore your backup to access your previous data and resume working.
Notify us if you need more help. We're here to guide you.
