These files are used by the Payroll program for a feature added in the Payroll version 3.6.3 and later. This feature checks our web site via the internet to find out is there is a new update or patch that needs to be downloaded and installed by the user. It is the ‘Check for Latest Version’ feature located in the Help menu. Windows 95 users may get this message if the computer they are running payroll on has never accessed the internet and therefore, an internet browser program has never been installed. Updating to Windows 98 solves this since the program, Internet Explorer, is part of the system install and thus, installs the needed .dll files.
