[Wine] How do i issue "msiexec /i msxml3.msi" in the terminal...

[GOgGA]

I found a way to install MS Office 2007 on ubuntu but the thing is i need to run something in the terminal. (Install msxml3.msi file from the Terminal window by issuing msiexec /i msxml3.msi)

I downloaded the msxml3.msi file and saved it to my desktop.

Now when i just put in "msiexec /i msxml3.msi" it gives me the following error (in the terminal): 

gogga at gogga-laptop:~$ msiexec /i msxml3.msi
err:msi:copy_package_to_temp failed to copy package L"msxml3.msi"
fixme:msi:MSI_OpenDatabaseW open failed r = 80030002!

I would like to know how to do it. I got this help from this site: http://www.quicktweaks.com/2008/04/09/install-ms-office-2007-in-linux/#more-5
