Sometimes it is quite difficult to determine why a game, a movie, or a document cannot be read on your computer. In the Windows OS environment, all these processes are responsible for executing files with exe permission. These are usually indicated by shortcuts on the desktop or quick launch bar. There are situations due to the operation of specific computers when these startup files suddenly stop functioning.
In order to find out the reason due to which the application does not start, check the file associations installed on the computer. It is possible that they were somehow accidentally violated. Also, file associations may be incorrect due to improper operation of the system or the actions of a virus that penetrated the computer.
Try to restore Windows OS to working condition using a utility. If this does not give positive results, you must manually correct the situation using the right mouse button and the context menu, in which you need to select the "open with" item.
If, after manually assigning the program, the exe file still does not open, then, most likely, a virus has settled in the computer, which has infected all startup files by changing the entries in the system registry. In this case, it is best to use special antivirus software.
If everything is in order with the file associations, and no virus was found, pay attention to the presence of a sufficient number of codecs in the system that are responsible for multimedia playback. Sometimes the software player does not start or crashes as soon as it starts. If this happens with a certain movie or video, then this is a typical situation of lack of codecs, without which the player cannot work correctly and will crash.
To see the processes currently running, open the Windows OS Task Manager. Review the list of running programs. Note that the application may appear in the process list but not in the program list. This situation occurs quite often and is the reason for the failure of a certain program, which by default cannot run simultaneously with its copy. This is how the Opera browser works, for example. Sometimes a software conflict occurs, the browser closes abnormally, it is not visible on the desktop and in the list of running programs, but the program still remains in the processes. And if the user wants to start the browser again, he will not be able to do so until he manually closes the still active process himself.
