I can't open Microsoft Word 2007 program and document

I have an Acer Aspire 4740G laptop, running MS Windows 7 Home Premium 64-bit, with Intel Core i5 CPU M 430 @ 2.27 GHz, and 2 GB RAM. I have AVG Antivirus Free Edition 2014 installed.

I have many problems and get error messages when I try to open a MS Word document or try to get MS Word program to open.

Problem #1 and Error message #1:

I cannot get past the first orange screen that says "Microsoft Word 2007". It hangs indefinitely. Error message: "There was a problem sending the command to the program."

Problem #2:

I tried to open a MS Word document with LibreOffice. It opened the first MS Word document but hanged indefinitely when I tried to open another MS Word document.

Problem #3:

I tried opening a MS Word document using MS Publisher; it had problems and hanged indefinitely.

Problem #4 and Error message #2:

I tried to create a document in MS Publisher using MS Word features (import) but it gave an error message: "Microsoft Office Publisher is connecting to printer Microsoft XPS Document Writer to get print capabilities and settings information." This hanged indefinitely.

Problem #5:

After I had imported MS Word features into MS Publisher, when I tried to use MS Publisher itself, the pull-down menus were all empty. Why were they empty? What happened there? It never happened before.

Problem #6:

I searched Windword.exe using Start > and I typed this in the Search box:

"C:\Program Files\Microsoft Office\Office12\winword.exe"/unregserver

But I didn't find this on my laptop. So I downloaded Winword.exe and searched again. But still this search term "unregserver" did not appear.

Problem #7:

I went to the Control Panel and clicked on "Programs and Features" then scrolled down the list until I found Word and clicked on it. Then it gave me an option to Remove/Modify/Repair. I clicked Repair but it did not 'repair' the program and I still can't open my MS Word.


I don't want to have to re-install MS Word because I have misplaced it and can't find it anyway.

I will sincerely appreciate any help.

I posted my problems earlier, and 2 people came forward to help - I am happy & TQ. I'm also happy because while waiting for help to come, I did something right - I updated Windows (there were 1 critical and 4 normal updates). I downloaded them but I don't remember whether I installed them or not. Then an exe window appeared and said it will repair my Microsoft Word 2007. I waited and another window said something else (to save document or smthg). I waited till the second window completed and said my program is completed and fixed. Then I tried to open MS Word program which I pinned to my bottom menu bar and it instantly opened. Wonderful! I have not tried anything else, not even the solutions posted above from the 2 who came fwd to help (archer and rich). I will write again if I get stuck. TQ. Now I can say "Happy New Year!"
