Greetings - Win 7 home premium 64 bit. Just trying to install open office (downloading from Apache open office.org) as I have on other machines in the past. After I save the file and try to install the program, I get an error window "windows cant open this file" it is evidently a .part (partial) file. Doing a web file association search reveals numerous frightening downloads that claim will solve this problem. Whats up ? Thx.
