How do I install a language pack?

[Urbicicuka]

I have a laptop with Vista. I recently converted the Office 2007 trial
(English) to the non-commercial version.

I need Hungarian proofing tools so downloaded the Hungarian language pack.
Was surprised that it is 280 megs (or more!). Paid for it, downloaded it. And
when I click to install

a) I get a message saying the publisher isn't recognised (perhaps not
significant)

b) The installation fails with an error message in Hungarian, saying
"installation failed."

Are we doing something wrong?

Just to add to my post:

I tried again and I do find it bizarre in the extreme that when I try to
install a Microsoft product, purchased and downloaded from the Microsoft site
(Hungarian language pack), the Microsoft operating system (Vista) does not
recognise the publisher! I tested by seeing how it reacts to the office
installation download previously purchased and this is recognised as
Microsoft.

Why is it that Microsoft are selling non-Microsoft software on its website?
And is this why it isn't working?

When I installed the German Language Pack purchased from the Office web site
I had to enter a "Product Key" that I obtained when I purchased it. This
worked the first time. Later when I reinstalled it to the same computer I
received an error message, "Aktivierung Fehlgeschlagen - unknown error" and
a "request code". I had to e-mail the request code to Microsoft Office US
in order to receive an "Unlock Code", which I then used for "Manuelle
Aktivierung" of the product. There is an e-mail address for Customer
Support on the Office web site you can use for this purpose. If there is a
45 digit long request code in the box that reports installation failure, you
are to e-mail this to them.

The "publisher" and also the "vendor of record" of the German Language Pack
is Digital River, but they had no record of my transaction when I e-mailed
them about the installation error. Apparently their function is to
implement the credit card transaction.

The German Language Pack is 331 Megs.

Hope this helps,
