.NET Framework is a very important component of Microsoft Windows which is highly essential for the proper installation and running of iolo technologies' products such as our flagship System Mechanic product line. The .Net Framework is normally something that is installed during the course of Windows applying patches and updates. However, sometimes Windows users put off, or otherwise defer, updating Windows and might fall behind in critical .Net updates that are essential for the proper running of installed software that depends on the framework. 

Iolo technologies' products always depend on the latest available version of the .Net Framework so it is essential to maintain it at the most current Microsoft released version. During the course of contacting iolo technologies Customer Care for product assistance, it is a requirement that the Windows .Net Framework be up to date so as to provide proper troubleshooting and support.
