Windows 10: Microsoft Professional Plus 2010 Activation Wizard

When I open Microsoft Word. It showed a window with an Error code: 0XC004F074

I need help understanding what is the problem with my Office. I have been using for 4 years and there's nothing wrong with it until recently.


Thank you.

“Microsoft Office Professional Plus 2010” vs “Microsoft Office Professional Plus 2010” PROBLEM!!!!

Some time ago my Computer crashed and I took it in for repairs and Data recovery which was successfully executed.

At the time of this unfortunate turnout of events, the Application Software installed in my Computer was “Microsoft Office Home and Business 2010”, which I had purchased myself upon the purchased
of the Computer and for which I still have the “Product Key”

It would appear that among other things, in the process of carrying out the repairs to the Computer and related Data Recovery, unbeknown to me my “Microsoft Office Home and Business 2010” Application
Software got replaced with “Microsoft Office Professional Plus 2010”.
“Microsoft Office Activation Wizard” “Microsoft Office Professional Plus 2010”
“Error Code : 0xC004F074”

The deadline period within which I was supposed to have “activated” the “Microsoft Office Professional Plus 2010” has come and gone. Needless to say, I did not even make any attempt at activation
because I do not have access to the Product Key relating thereto. Thankfully the Application Software is still functional though, but I now get pop-ups of “Microsoft Office Activation Wizard” Prompts which, among other things
advise that “This copy of Microsoft Office is not activated”. Also of
major concern is the fact that each time upon opening Word, Excel or Outlook one gets a
Red Banded
Cautionary pop-up at the top of the Screed advising that (Product Activation Failed).THE FACT OF THE MATTER IS THAT I HAVE NO INTEREST IN ACTIVATING
Microsoft Office Professional Plus 2010–
!

I have no idea how long the “Microsoft Office Professional Plus 2010” will remain functional in my Computer notwithstanding the cautionary prompts relentlessly popping up advising that “This
copy of Microsoft Office is not activated” and that (Product Activation Failed).

The bottom line is that I would like to have the “Microsoft Office Professional Plus 2010” uninstalled and in its place install my “Microsoft Office Home and Business 2010”.
The BIG question is :

“HOW TO DO THAT WITHOUT RISKING THE POTENTIAL LOSS OF VOLUMES OF DATA ALREADY IN MY COMPUTER”.

ASSISTANCE AND GUIDANCE IN THAT REGARD WOULD INDEED BE VERY MUCH APPRECIATED!!!

 

Activate Microsoft Office Professional Plus 2010

Now I got the key and have installed the Microsoft Office Professional Plus 2010 but when I opened any Microsoft apps it still required the Product Key

 

Error code:0x8007007B while activation of MS-Office Pro Plus 2010

One month ago, I have undergone a virus software attack leading to reset of my pc, all of my files were intact, just applications and features were removed. Then I installed Microsoft Office Professional Plus 2010, and now I am getting this notifications regarding activation key. Look at the screenshot below.





Then, I entered Product key, it was perfectly accepted and the and the installation process was then completed.







But, then, when I relaunched the programme, it again asked me for activation Key. However times I enter and make my MS product validated, in the very next time, it always shows me that obnoxious Activation Wizard.

I have seen this discussion, none of the workarounds suggested there, worked for me. I never got an run as administrator option upon right click, which was one of the suggestions stated there.

Also, followed some discussions like this, this and this, but those are different problems.

Just the link of discussion in MS site was reasonable, but that didn't solve my problem.

Any way out?
