To create the modern software product properly and then test it and search out all the errors, that were made during the process of programming, tools for software developers can be used. This software is not the application oriented or system program, this is used just by the programmers. Programming of the action of installation is very important and should be performed by programmer very thoroughly. Before the modern programs appeared, there were no troubles with installation. The user had to copy the files to any directory of the hard disk. The software could be run without any other actions done by operator. The program couldn't be run rightly just if it wasn't supported by the CPU. Today any program designer must know that to create a successful software program he should utilize the special utilities called install utilities. Any driver or application can't operate correctly if it wasn't installed with this special sort of software. Different installers are created for installing the files comprised inside of it, others are considered to be versatile and they operate reading the substance of the package of the programming software, which needs the installation. Windows OS has got a lot of advantages. One of them is that the process of installation became simpler than it used to be in MS-DOS. The program comprises the row of commands that should be executed in the given sequence. This mechanism has to be transformed into the programming language.

Unfortunately, most of programs don't comprise all these commands into the one file and the way of easy access to it not always exists. The application can utilize hundreds or even thousands of files that can't be placed on one information carrier. So, any program can't do without special additional installation software. The applications designed for Windows usually perfectly get all the needed information about the hardware. The installer will automatically search out all the necessary data about the computer without any help of the operator. Before the process of creating of new software is completed, debugging has to be performed regardless of what kind of soft it is. To fulfill the debugging properly the unique software debugging should be used. Only performing the step execution of the product all the errors can be found. This method allows finding the mistakes in the initial code of the product. If the mistake exists the operator can see it during the application is run step by step. All the values of constants are shown for the programmer in the debug mode. Debugging is quite hard and wearisome task. Such programming languages as Java are quite appropriate for debugging. They comprise the unique component named exception handling. Having it used the programmer will simply search out the origins of the problem. Different problems can't be searched out even if the step by step test running has been performed carefully. For instance, it could be the damage of memory or the memory leak. These problems can be found only by means of utilizing some additional debugging programs.
