Ok, the net connection for my rtw computer isn't working, so I downloaded 7.5 to another computer and installed. I now plan to copy the files I need onto a flashdisk and install it on my rtw computer. Problem obviously is that the flash disk can't do it all at once. I only intend to play BI for the moment, so I assume it is ok to copy just what is in the BI folder (ie the BI doesn't share files with rtw??)??
