Mazliet Googles...
"Actually, there are multiple reasons why a document might say this at the bottom:
1) You are using a trial, or unactivated version of Word - buy the product and activate it
2) some portion of the document may be protected (access via Developer toolbar) - the solution is posted above
3) And this one took me a while... [Office Button] -> Prepare menu has a "Mark as Final" option that makes a document Read Only. If this has been done, there is an icon in the Status Bar (to the right of the Word Count) that says "Marked as Final" when you hover over it. To undo, just go back to the Prepare menu as select the "Mark as Final" option again."

Visticamāk palīdzēs 1) piedāvātā iespēja.

Man rāda, ka Office ir activated un validated...

Vēl jau paliek 2) un 3) iespēja, bet ticamāk, ka jāatgriežas pie pirmās.

Ja Office tiešām ir legāls un aktivizēts, tad varētu palīdzēt pilnīga tā izravēšana (skatīt kb928218) un pārinstalēšana. Saskaņā ar avotiem Googlē, esot iespējama situācija ar liekiem ierakstiem reģistrā (saistīts ar trial versiju, kas bijusi datorā). Piemēram:
"Success!!!!
I had a look at the registry and found that there is a huge mess with the
Trial version values over-writing anything you do.
Found details at article id 928218...even if you can Uninstall MS Office, do
that and then follow the instructions to delete all traces, especially from
the Registry.
I have now reinstalled and it asked me to Activate and it works!!"
