UPDATE
Although I was able to install MSOffice 2007 in 64bit architecture, I could not open an existing docx file or save a new file. I kept getting errors such as 'Open xml file <file name> could not be opened'. Subsequently, a 'Configuration Process' window opened and stopped half way with another error message.
Then I removed the virtual drive and re-installed Office in 32 bit architecture and now I have no issues with opening or saving files.
Just sharing this info if someone else comes across the same issue.
If anyone can shed some light on this problem, it will be greatly appreciated.
EDIT : Should have read earlier....as per WineHQ, Winword works on 32 architecture only!
