I had some issues with getting an Office 2013 Professional Plus 2013 trial when I first installed it from TechNet, and I had to reinstall it. When I tried to activate it after reinstalling, I got the error Error 25004. The product key you entered cannot be used on this machine. This is most likely due to previous Office 2010 trials being installed.
I didn't use up my trial period, and I only had it running for about a day before uninstalling it. I've tried everything, removing registry keys (HKLM and HKCU\Software\Microsoft\Office), removing files from Program Files, AppData, and ProgramData, and even got rid of some files from C:\Program Files\Common Files (Office, OfficeSoftwareProtectionService, Source Engine).
I really don't want to have to format my hard drive and reinstall Windows.

I had this exact same problem. Mine was to do with the KMS activation failing after I mistakenly installed a O365 Small Business on a server and later realised I would need a VL install for terminal services RDP sessions. No matter what I did or what registry entries I deleted it didn't work. One person suggested (This worked for them, but would not work for me):
C:\Program Files\Common Files\microsoft shared
OFFICE15
orOfficeSoftwareProtectionPlatform
, delete that folder.C:\Program Files (x86)\Common Files\Microsoft Shared
OFFICE15
orOfficeSoftwareProtectionPlatform
, delete that folder.http://answers.microsoft.com/en-us/office/forum/office_2013_release-office_install/office-2013-activator-error-25004-even-after/eed3a057-4ff9-401d-af49-04c0262223af
So after hours of messing about, I figured out a work around. This will only help you if you can use a MAK key.
setup.exe /admin
(examplec:\2013>setup.exe /admin
)2013.msp
) and save it to the updates folder within you office install. (egC:\2013\updates\2013.msp
)setup.exe
as per normal. (you may need to run as admin if required)This worked for me and I hope it solves your issues too.
