Fix Cannot access the Windows Installer Service

Windows Installer fulfills a function as a service that Windows comes installed by default as a Windows API that performs tasks of installing and uninstalling applications or software items on our PC. It makes use of packages that contain data that this service needs to be able to perform tasks with a software product. That is why sometimes if we do not have access to Windows Installer it may lead to certain problems on the computer..

 

In Windows 10 or Windows 11 many of the system processes are based on services which allow all processes between system and user components to run accurately, one of the most notable Windows services is the Windows Installer service. . This is a service that is responsible for adding, modifying and removing applications that have been delivered as Windows Installer packages (*.msi, *.msp, *.appx). As the service is disabled, none of the services dependent on it can be used in the system, this is the cause of seeing the error "Windows Installer service is not accessible" but TechnoWikis has a solution for this error.
