I found this official link 1 hour ago after searching for 2 years.

I own an Office 2007 Student Pack in Italian - but I'm used to excel formulas in English,
and to have all Office in English. The interface being in Italian it's a pain.

Microsoft 2 years ago discontinued the support for language pack support,
I was pointing there to change interface every-time I had to reinstall.
The PC Main Disk crashed, and over the pain to do the full install of everything,
I discovered that I was stuck with an Italian Office !

Now they came back and offered a good solution ... full download of the older Office version ... any language.
(only 32 bit)


Hope it will help some other People out there !
