Installation guide
Last updated: September 11, 2026
Before you install
- Close AutoCAD completely.
- Make sure you have administrator rights in Windows.
- Download the installer from the Downloads page in your account.
- Check the file's SHA-256 checksum once the download finishes — the checksum is published on the release notes page.
The command to read the checksum in Windows PowerShell:
Get-FileHash .\NB_Engineering_Tools_Setup.exe -Algorithm SHA256
Installing
One setup supports AutoCAD 2024, 2025, 2026 and 2027.
- Run the installer, read the EULA and accept it.
- Select which AutoCAD versions to install into.
- When it finishes, open AutoCAD — you get both an NB tab on the Ribbon and the classic pull-down menu.
Upgrade, repair and uninstall
The same installer runs upgrade, repair, uninstall and rollback. It keeps its own log of each step; attach that log file when you write to support.
If the menu does not appear
- Run
MENULOADin AutoCAD and check whether the partial menu is loaded. - Check that the NB folder is listed under
OPTIONS → Files → Support File Search Path. - If that does not fix it, run Repair from the installer.
