  • Hi Andrew,
    I’ve installed Microsoft office 2013 professional plus trial (60 days) iso on a freshly formatted computer from a microsoft iso image and didn’t activate it yet.
    When I checked the office installed product key (Via nirsoft Product key viewer),I saw a product key that ends with 27GXM. Each time I open office program (word, excel) – I am asked to activate it.
    I bought an office 2013 pro plus licnese, And entered once I was asked to activate office, And it activated my office copy online.
    When I went to see if product key has changed, In nirsoft program I see the old one that ends with 27GXM.
    I followed your guideline to remove the 27GXM key from office key,But the 27GXM stiils seems to be the activation code in some programs that I check (Nirsoft product key viewer, Advanced token manager 3.5).
    When I run the command prompt Dstatus command, It does show me it is activated with the correct key.

    Any help will be appreciated in understanding why is that.

    Thank you

  • Im impressed, I should say. Pretty rarely do I come across a blog thats each informative and entertaining, and let me let you know, youve hit the nail on the head. Your blog is significant; the problem is some thing that not sufficient men and women are talking intelligently about. Im seriously happy that I stumbled across this in my search for one thing relating to this issue.
