I am Microsoft software developer for more than 20 years, with high skill in data processing and automation (look at my portfolio).
I have developed applications for companies in many sectors (industrial, healthcare, commerce, manufacturing, government, financial, servicing, etc.) and for all major business operations (administration, production, stocking, provisioning, employees management, customer service, etc.).
My proposal consists of a desktop application which generates the serial codes using the desired formula.
The application is developed in VB.net, therefore it does not require Microsoft Excel and can run on any Microsoft operating system, starting from Windows XP onwards and on 32 and 64 bit.
The desktop application shall be accompanied by a simple procedure for fast installation on PC.
What do you mean for: it should require each installation of the program to have a unique serial number/licence code ? Each installation must generate different pairs of serial number/license key ?
If you are interested with my proposal or need more information feel free to contact me on Freelancer's chat, because only the employer can start the comunication with freelancer.
