Windows – Office 2013 Trial Error 25004

microsoft-officemicrosoft-office-2013product-keywindows 8.1

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):

So after hours of messing about, I figured out a work around. This will only help you if you can use a MAK key.

  1. Uninstall any versions of office 2010 or 2013 you may have installed. OBVIOUSLY :)
  2. Run the office 15 Click-To-Run remove tool.
  3. Reboot if required
  4. Copy your Office CD to your HDD (you need to add some install instructions)
  5. Launch and admin command prompt and navigate to where you copied your CD files. Then run your office setup with the command - setup.exe /admin (example c:\2013>setup.exe /admin)
  6. This will launch the Office Customization tool.
  7. Go to Licencing and user interface - select enter product key - load in your MAK key with no spaces (it will insert dashes) - accept the licence agreement
  8. file - save - and name the file (eg. 2013.msp) and save it to the updates folder within you office install. (eg C:\2013\updates\2013.msp)
  9. exit the tool and command and run 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.
