A family of Microsoft word processing software products for creating web, email, and print documents.
Which version of Office are you using? For Office 2013, proofing tools can be downloaded for free from http://www.microsoft.com/en-us/download/details.aspx?id=35400. Office 2010 language packs can be purchased via http://www.microsoftstore.com/store/msusa/en_US/pdp/productID.253665800?cdid=[lc].
It's irksome that someone would have to purchase a language pack for a program that has worked without a hitch for years. Spellcheck & other proofing tools (for English) came with the program in the first place.
In addition, Word extensions have changed some .docx files to .doc & they won't open ~ on 2010 that shouldn't make a difference as it is supposed to open.doc files which you can then save-as .docx for future use. Still, it should NOT suddenly change document extensions like that.
As there are other issues on my computer, (clock doesn't keep time no matter how many times I reset or re-sync it &/or replace the battery) sometimes the computer won't boot properly, virus scanners can't find anything wrong, malware programs dig out Advertising cookies by the dozens) ... I am beginning to think it is the Motherboard.
Re-installing Windows 7 and Microsoft Office 2010 is likely to be a waste of time, with troubles of it's own.
I'd like to THANK all of you who've shared your knowledge & procedures for correcting any of this. Your instructions have been easy to follow and in the very least, with your help I have combed through this computer from end to end and have learned more than I ever thought I could about the innards & workings of computers!
In the end, I think it's time to put this old thing out of its misery & look for a new computer. I am grateful for your help! *mary
