During DQNB installation, the following error might be prompted due to fail to install 32 bit Microsoft Database Engine 2016. 


If you see this error, please click OK to ignore this error for now and continue to finish the installation. Once the installation is done successfully, please try to open DQNB client. 

If you get the error below while try to open DQNB client, then please install one 32bit microsoft database engine manually. The one that we usually use is 32bit Microsoft database Engine 2010. You can download it through this link,  Microsoft Database Engine 2010 32 bit




DQNB License Key Activation Error
User Case: The Digital Quality Notebook (DQNB) cannot activate my license key and it shows the error "Failed to Activate the License Key."
This problem can occur when HLsksvc service is not wrong in windows. Please try to open Services in the PC , start/restart HLsksvc service and then try to activate the license again in DQNB Client.
The DQNB Crashes when I click on "Generate Document"

Q: The DQNB Client Tool crashes after I click on "Generate Document" without any prompted error message. What is the cause of this crash? 

There are some situations where the DQNB Client Tool Version 1.1.10 crashes while in the process of document generation without any prompt.

While debugging it is observed that, the application was updated to use the latest API call (SaveAs2), which was not supported in MSWord2007. Now, this issue is fixed and the API call is updated to be compatible with Word2007, 2010 and 2016.

 Initially, our development and test systems were installed with Word2007 and the initial Client Tool releases were tested with Word2007. After upgrading to Word2010/2016 in the systems, the application was not able to be tested in Word2007 and this issue could not be identified. Sorry for the inconvenience.

 Also, Word2007, by default does not support PDF file generation. It needs an add-in to be installed separately. Whereas Word2010 and above inherently support PDF generation without any add-in. We are looking to detect and install the plug-in automatically in Word2007.

What is the DQNB, and What Does it Do?


The HunterLab Digital Qualification Notebook (DQNB) is an industry 4.0 digital workflow enabled software solution designed to facilitate simplified user creation of a comprehensive Validation and Compliance “Qualification Notebook” for HunterLab instruments. Generating easy to follow step-by-step instructions, DQNB provides instrument and application-specific IQ, OQ, and PQ protocols and documentation that are used to validate proper instrument installation and performance for the intended application.

The DQNB software incorporates a simple user interface that allows a user to input their company information, select their sample type(s), and select any accessories that they purchased with the instrument that will be used for color measurement of their samples. In a few easy clicks, the DQNB Document Generator uses these inputs to generate the appropriate Validation and Compliance notebook, which can be printed out, placed in a binder and used to document the IQ, OQ and PQ processes.

The Foundation for Good Manufacturing Practice (GMP)

Customers in highly regulated industries like food and pharmaceutical are familiar with the need for thorough validation of equipment and processes as part of Good Manufacturing Practice (GMP). Validation is a valuable tool in the design, development, and production of all products, and plays a vital role in defining the success of a product in both technical and economic terms.

HunterLab has been at the forefront of helping their customers validate their HunterLab instruments and equipment to achieve regulatory compliance in many industrial markets, and has helped many customers in non-regulated markets to build their quality control process on a solid foundation.

Whether you have purchased a new instrument, have recently had your instrument serviced or updated, or have simply moved your instrument to a new location, DQNB provides everything you need for initial and ongoing instrument validation.
