These errors can be rectified by then installing the required software components. Apache is written in C++, meaning the programme requires an appropriate run time environment when used on a Windows operating system. This is available through the compiler software Visual C++.
Missing run time components can be installed with the Visual C++ Redistributable Packages. These are available to download for free from the Microsoft Website and can be installed by simply double clicking the .exe file.
Windows security warning
Generally, PCs are safeguarded by a firewall, which prevents external programmes gaining unauthorised access to a system via a network. If, however, you would like to make your local Apache HTTP server available on a home or work network, you need to explicitly authorise the communication with Apache. This can be done in the security message that follows, which reports that some of the web server’s functions are blocked by the Firewall.
