I was able to burn the software to a disk with no problems. When I attempt to install, I get an error message "Error 25004. The product key you entered cannot be used on this machine. This is most likely due to previous Office 2013 trials being installed. System error: -1073422314."  The install process never asked me to enter a product key. I am running 32bit and downloaded the 32 bit version. I am also running Office 2010, except Outlook is the 2007 version. Thanks for any suggestions.

Hi,
The message 25004 could indicate problems with the trial product key, I think MicroSoft thinks it's been used on this machine, so lets go back and start over again.
Please try to do following steps:   
 Get a new trial product key, may need to create a dummy email id to get it.
 Uninstall current trial, use FIX IT from KB290301 and confirm with manual process confirmation msl
 reboot into safe mode (with networking)
 clean TEMP folder
 install new trial (in safe mode)  (I dont know how they did this since in Vista I get message Installer service cannot be starter

Thanks for the advice. Unfortunately these steps didn't resolve the issue.

Hi,
Did someone install the Visio 2013 Trial version in the computer?
As far as I know, the Trial version only can be used for 60 days in the same computer.
If you need to use, please refer to the following link:
