The Microsoft .NET Framework 4.7.2 is required to run applications on
Windows environments. F-Secure products, such as F-Secure SAFE (as of release
17.6), will require this version of .NET Framework to be able to show the
product user interface.
Normally, during the installation of the F-Secure products, our
network installer will automatically try to install the .NET Framework if it is
missing from the environment. If, however, the installation of the .NET
Framework fails, the user gets an error message which includes a link to
information on how to install the .NET Framework manually.
