The common problems during the process of software creation

To project, design and support some new software products such detached class as software development tools is utilized. That software is not the application oriented or system software, it is used only by the programmers. Programming of the action of installation is very important and should be performed by programmer very thoroughly. Until the modern programs appeared, there were no troubles with installation. The application file had to be just copied to any directory of the HDD. MS-DOS didn't require any extra actions. The program couldn't be run properly only if it wasn't approved by the CPU. To achieve the success in creating the software any programmer has to use special setup utils. This is actually indispensable today. Any driver or application won't operate properly if it wasn't installed using this special kind of software. Some installers are made for installing the files comprised inside of it, others are considered to be universal and they work reading the content of the package of the programming software, that needs the installation. Windows OS considerably simplifies the process of installation the software, if the developer of program uses all the advantages of that operation system. Creating the software, the programmer gives the sequence of definite commands for the PC and then they are transformed into the special code that is read by the system.

Unfortunately, most of programs don't comprise all those commands into the single file and the way of easy access to it not always exists. Very often they are placed in some quantity of files that can be located even on several different information carriers. So, any program can't do without unique additional installation software. The applications created for Windows generally perfectly get all the needed information about the system. The installer can automatically find all the necessary information about the system without any assistance of the operator. Before the action of designing of modern software is completed, debugging must be carried out regardless of what sort of soft this is. To fulfill the debugging rightly the unique debug utilities can be used. Only the step execution of the application all the mistakes can be searched out. Operation by operation, function by function the application is run and it is halted when reaching definite line of the initial code or if the definite condition is reached. All the values of constants are shown for the operator in the debug mode. Actually that is not so simple to perform the correct debugging. The action of debugging is easier if the product was created using such programming language as Java which comprises the unique tool called exception handling. Having it used the programmer will easily search out the origins of the complexity. Various problems can't be found even if the step by step test running has been performed carefully. For example, it could be the injury of memory or the memory leak. And it is really complicated to determine the initial origin of the mistake. In such instances different sophisticated debugger software can be demanded.
