Extend the Office 2013 Trial by 180 Days

renew subscription

Microsoft usually releases a trial version of its software. Office 2013 (Office 365) is no exception and comes with a 30 day preview. However, Microsoft also included a tool that resets the trial time, it can be ran a total of 6 times. This gives us 6 x 30 days = 180 days of free Office 2013. Not too bad for the price!

It doesn’t matter when you do the re-arm, so if you aren’t going to be using Office 2013 for a while just wait until you need it. This potentially gives you more use, as there aren’t any downsides to letting the software run out of time before applying the trial reset.

To  rearm Office 2013 only takes a few steps. Firstly, visit the following folder.

Once there, use hold the Shift key down and right-click on the following folder:

    “OSPPREARM.EXE” is present in “C:\Program Files (x86)\Microsoft Office\Office15”. You will have to run command prompt as an administrator.

    tried the above and am now getting…

    There was an error when trying to rearm Office. You can try passing the SKU ID as a parameter. Passing the SKU ID is necessary if you are relying on an activivation to permit an additional rearm.
    Error: 0xc004f025
    On a computer running Microsoft Windows non-core edition, run ‘slui.exe 0x2a 0xc004f025’ to display the error text.

    What should I do?
