When upgrade your NBS program you get the error 'Please insert disc 1'. It is then not possible to complete the installation.


This is caused by a conflict with Windows Installer. 

The easiest way to fix this is to uninstall NBS then reinstall it. Use the latest major version - every update we release on our downloads is the full program. 

Alternatively delete the MS Windows installer registry key for the NBS program you are trying to update. This registry key informs the machine how the software was installed and must be deleted. 

  1. To access the registry, click on Start > Run or Search and enter regedit. Please ensure that you have appropriate permissions to modify the registry.
  2. The relevant key is located in HKEY_CLASSES_ROOT\Installer\Products
  3. Scroll down the keys in the left panel while looking for the product key in the right hand panel. You are looking for the NBS program you are working on.
    and delete.  
  4. Reinstall the program.
