Read more about how these components work with Point of Sale

What is Microsoft .NET Framework?

.NET is a framework component Microsoft uses to interface programs through Windows.

Point of Sale uses .NET for many parts of the program in order to function properly. Different versions of .NET are used for different versions of Point of Sale. It's possible for .NET framework to become corrupted, causing functional issues within the Point of Sale program, during install, or even when trying to open.

What is MSXML?

Microsoft XML Core Services (MSXML) is a set of services that allow applications written in Script, VBScript, and Microsoft development tools to build Windows-native XML-based applications.

XML is an almost universally supported way of exchanging documents and data across applications and platforms. In other words, it's a way of organizing information so you can view data easier.

Microsoft has provided MSXML as a middle-man to interpret data between XML documents and Point of Sale.

What is C++?

The Microsoft Visual C++ Redistributable Package contains library files required to run applications developed with Visual C++, in which Point of Sale was written.

If a computer does not have the correct version of Visual C++ installed, Point of Sale will install it automatically.
