I have installed a legitmate copy of Windows 7 onto virtualbox using a live CD and installing the guest OS. But when I go to run the installer for office 2007 it gets halfway and then says setup cannot find setup.exe.
Try copying the whole cd(s) into a directory (folder) in Windows and run it from there. This worked for me with an earlier copy office. The same goes for any Windows app really.
I have used the disk after on my windows partition and it installed fine. The problem with moving over to libreoffice is that I can't open files. I need this for my maths homework. Otherwise I would make an effort to switch.
Somehow I got it working! think it was to with permissions where I wasn't part of the vboxusers. I think I overlooked this on the video. Maybe it was to do with my graphics drivers that I have got somewhat working (the open source ones on the xorgs ppa) meaning I can now play CS GO with some stutter on everything including my browser.
