The essential information for program producers

To create the new software product duly and then check it and find all the mistakes, that were done during the action of programming, programmer utilities should be used. This software is not the application oriented or system software, it is used only by the producers. Installation is a very significant part of the created program. The operational features of the program depend on it. Only several years ago there were no complications with the installation. The user had to move the files to any directory of the HDD. MS-DOS didn't require any additional actions. The only demand was the conformity of the equipment. To reach the success in designing the software any programmer has to use special installation tools. This is really necessary today. It is used to install all the possible kinds of files, such as applications, drivers, etc.. Different installers are created for installing the files included inside of it, others are considered to be versatile and they operate reading the content of the package of the programming software, that needs the installation. Using the Windows OS any user is able to execute the process of installation properly, even if he is not an advanced user. The program includes the roll of commands that should be executed in the definite sequence. This algorithm has to be converted into the programming language.

Unfortunately, most of programs don't include all those instructions into the single file and the way of simple access to it not always exists. Frequently they are placed in some quantity of files which can be located even on several different information carriers. So the installation software is a constituent of any software program. The applications designed for Windows usually perfectly gain all the necessary data about the hardware. They can automatically search out all the needed resources such as HDD, sound and video chips, etc. The definitive phase of designing any modern software is debugging, which assists to detect, restrict and correct all the mistakes. As the main means of the debugging the debug programs can be used. Step execution of the product is the main idea of any debugging action. This method permits determining the errors in the initial code of the product. If the mistake exists the programmer can see it during the program is run step by step. All the values of constants are shown for the programmer in the debug mode. Debugging is very hard and wearisome task. The action of debugging is easier if the program was designed using such programming language as Java which comprises the special instrument named exception handling. Having it utilized the developer will easily search out the origins of the problem. In various programming languages as C or assembler errors can cause the unnoticeable problems. Some of them are damage of the memory or the memory ooze. And it is not always obtainable to determine the main origin of the definite mistake. In such instances different sophisticated debugger software can be needed.
