ZIP archive that contains the program. Version 1.7.1

For its simplicity, we distribute the product as a ZIP package. This can be unpacked by Windows XP operating system or using other product like Total Commander, WinZIP, WinRAR or others. Because the product allows you to associate the .log extension to it and to add context command to open a file (right mouse button, command "Watch file as log..."), the advice is to unpack the file into well known location (like Program Files folder) and use these functions.
