Windows - Unable to run executable files (. Exe)

April 2016

Sometimes, users may be unable to run executable files if there is a configuration error in the computer or a virus problem. In such cases, users will be unable to launch Windows programs. The problem while running exe files can be solved in two ways. Firstly, check the configuration of the Windows system. Secondly, the operating systems can show unpredictable behavior if they are infected with a virus. If the system is unable to run executable files, even if the configuration settings have been corrected, it could have been infected with a virus. If so, the system has to be disinfected.
