I can't download the newest version

I am trying to download the ver. 6.60 but it can’t be completed. Although I have installed other previous versions, when I open the Excel file the XL Toolbox add in is not activated. Please, do you have any suggestion? Thank you!

It seems that some of the download servers of Sourceforge have broken files… Try this direct link: downloads.sourceforge.net/projec … x_6.60.exe
