To design the modern software product properly and then test it and search out all the errors, which were made during the action of programming, programmer utilities should be used. This term is commonly utilized to separate that type of software from application oriented and system software. One of the most important phases of creating the modern program is designing the installation system for current product. The previous generation of software didn't have such complexities with installation. The operator had to copy the files to any directory of the hard disk. Then it was started by the common means of MS-DOS. If the program was compatible with the CPU, it run properly. To reach the success in creating the programs any programmer has to use special installation tools. That is really necessary nowadays. Any driver or application can't operate duly if it wasn't installed using this special sort of software. Some installers are created for installing the files comprised inside of it, others are considered to be versatile and they operate reading the content of the pack of the programming software, which needs the installation. Using the Windows OS any operator is able to perform the action of installation easily, even if he is not an advanced user. In general, the program is the pack of definite commands for the PC which have to be executed in the given time and sequence.
Most of modern software products can't be included into the one file. There are many different additional files which are used by the main application. Frequently they are comprised in some quantity of files that can be located even on several different information carriers. So, any program can't do without special additional installation software. The applications created for Windows usually perfectly gain all the needed data about the system. The installer can automatically find all the needed information about the computer without any help of the operator. Debugging is the phase of designing the software program that finds, restricts and corrects all the errors. To fulfill the debugging properly the special debug utilities can be used. They comprise the user's interface for step execution of the program. This method allows determining the mistakes in the primary code of the program. If the error exists the programmer can search it out during the program is run step by step. They also allow monitoring of the values of constants. Debugging is quite complicated and exhausting action. The action of debugging is easier if the product was designed using such programming language as Java that includes the special instrument called exception handling. Origins of the problems can be simply searched out if the developer utilizes such software. Different problems can't be searched out even if the step by step test running has been executed carefully. For instance, it could be the damage of memory or the memory ooze. These problems can be searched out only by means of using some additional debugging programs.
