Installing microsoft office 2007 issues

hi all, I am installing office 2007 from my companys software hub.

installation has got to 85% complete and has now stalled. Task manager still
shows it as running though. Updating registry box is stopped at 85% and
'copying word...MUI.xml is at 86%.

I got an area saying something about powerpoint being unabl;e to install a
particular media add-on. i clicked ok to that error message and the
installation hasn't moved forward since.

when i go to start, Menu, it says new progams installed and office 2007 is
showing up. I've opened a document in word and it opens up in 2007.

Any ideas?
