What is the difference between data and program?

The program consists of files with extensions 'exe' and 'dll'. These are the instructions which tell the computer how to perform the calculations and drive the user interface, they cannot be altered by the user and do not change while the program is running. The data is made up of two parts:

1. The details of the profile dimensions, when and how those profiles are to be joined, reinforcement, fittings, glass types etc.
2. The details of the jobs and quotations which the user enters.

When we talk about data we are usually referring to the first part.

How can I find out where my data and program have been installed?

You can check the icons created on your desktop to find out where your program and data files are installed. Select the icon and right click using the mouse. On the menu that drops down, select Properties. The path indicated by 'Target' is where the program files are installed and the path indicated by 'Start In' is where the data files are installed.

About Windowseller
How is Windowseller licensed?

Windowseller works on hardware lock (Dongle). During installation, the program creates an encrypted license file that uniquely identifies the program with a computer.

What is a License File and why do I need to backup the license file?
  • When Windowseller is installed on a PC, it creates an encrypted license file in the installation directory called Ws3-4420.slx. If you have purchased Windowseller , it is vital that you back-up this file to a safe place.
  • Otherwise, if you have to perform a format, Windowseller will revert to unregistered status when reinstalled. If this is the case the above file can be copied into the installation directory (overwrite the existing .slx file) which will restore the license on the PC (status will change to 'Registered Copy' again).
  • After registering Windowseller, always back up the Ws3-4420.slx file to a safe place! If the hard disk fails and has to be replaced and a new license will have to be purchased, the slx file will not work with the new hard disk. A commercial user should insure against computer failure.
How will I get a User ID and Password?

The first time you upgrade you will be provided a User ID. Also, if you upgrade to any one of the options below you will be provided 'SUPERVISOR' as the User Name and a 'Password' to login to the program.

  • Costing/Pricing.
  • Upgrade from 250 to 9999 Quotes/Jobs

How do I create Windowseller data?

Windowseller data is created in Windowmaker by using the 'Create Windowseller data' menu entry available in the 'Tools' menu. For further details please refer to the 'How to Create Windowseller Data' section in the Windowmaker Help system.

When I update my data, can I provide these changes to the Reseller?

Any changes in the Supplier data will have to be provided to the Reseller by creating new Windowseller data. You can provide the updated data to the Reseller. However, this data will not contain any of the changes that the Reseller has done in the previously provided data. If you have made only costing/pricing changes, you will just have to provide a new WM. CFG file that reflects these changes. Before providing the new file, ensure that your data version matches with the data version being used by your Reseller.

Windowseller works most efficiently with Supplier data. Once you have received the data from your supplier you will need to download some standard files available on the website. In this case the supplier (fabricator) needs to be running the Windowmaker program.

Can I have data from more than one supplier?

Yes, you can have data from more than one supplier. The data of individual suppliers should be kept in separate folders and the Windowseller program in a different folder such that the program can easily be run on any data.

When I create a window the program says it is impossible. What is the most likely problem?

The most likely problem if you cannot enter a specific type of window is the way the data has been set-up. Whenever there is an error the program goes into 'wire frame' mode. The error dialog indicates the nature of the error.
