I have a Mac OS X Lion and would like to run Windows programs which are only programmed to run on Windows. What do I need so that I can run Windows and Microsoft Word.
Your tag says you have MS Office for Mac so if Word is mostly what you want, the Mac version of MS Office should do the trick. If you need to run other Windows-only software, your timing could be better. You can run Windows directly on the Mac using BootCamp, but Windows 8 is what's out there now and I don't know if BootCamp is compatible with Win 8 yet. You could also install Windows as a virtual machine in VMware Fusion, Parallels or Virtual Box. Or use CrossOver, which emulates Windows without having to actually install it.
If you use a virtual machine approach, you can add an extension which makes Windows 8 look and behave remarkably like Win 7.
"I have a Mac OS X Lion and would like to run Windows programs which are only programmed to run on Windows."
Your best bet is to use VirtualBox to provide a virtual machine capability allowing the installation of a guest OS like windows. I've used VB extensively for years and I highly recommend it's use for your issue.
If you have a full version of windows, you could use bootcamp as an alternative to VB but you lose the ability to access the OSx environment while booted in windows.
Best of luck
