To project, develop and support some new programs such separate class as programmer tools is utilized. That software is not the application oriented or system program, this is utilized just by the programmers. Installation is a very important part of the created program. The operational performances of the program depend on it. Just a few years ago there were no problems with the installation. The user had to copy the files to any directory of the HDD. Then it was run by the common means of MS-DOS. The only demand was the conformity of the equipment. To achieve the success in creating the programs any programmer has to use special setup utils. This is actually necessary today. Any driver or application can't operate properly if it wasn't installed with this unique kind of software. Different installers are created for installing the files comprised inside of it, others are considered to be universal and they work reading the substance of the package of the programming software, which needs the installation. Windows OS has got lots of beauties. One of them is that the action of installation became easier than it used to be in MS-DOS. The product includes the row of instructions which have to be performed 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 simple access to it not always exists. Very often they are placed in some number of files that can be located even on several different data carriers. So the installation software is an integral part of any software program. No other actions are demanded, excluding the process of installation for the right usage of the program which is compatible with Windows OS. The installer will automatically search out all the needed information about the computer without any help of the user. The definitive stage of designing any new software is debugging, that assists to detect, localize and correct all the mistakes. As the principal means of the debugging the debug utils should be used. They comprise the operator's interface for step performing of the application. The application is running step by step and the developer is able to halt it to test the performance of definite complicated instructions or the execution of different conditions. All the constants and variables are checked during the whole period of debugging. Actually that is not so simple to carry out the proper debugging. Using such programming languages as Java truly simplifies the process of debugging, because it comprises some unique means of exception handling. Origins of the problems can be simply searched out if the programmer utilizes this software. In different programming languages as C or assembler mistakes can cause the unnoticeable problems. For example, it could be the damage of memory or the memory ooze. And it is actually complicated to find the initial origin of the mistake. In such instances some sophisticated debugger software can be needed.
