Recently I was trying to install the trial to Microsoft Office 2010 so that I could work on a school project (that's due TOMORROW), but I ran into a problem. After downloading the exe file to install it, I ran it, put in the given serial code, then let it install. Everything was going alright for the first few seconds, until it told me that it ran into error 1303. It's telling me about how it can't open C:\Program Files (x86)\Common Files\Microsoft Shared\Equation\1033, and that I should verify if it exists and make sure I have permission to edit it. Now, it does exist, but I can't open it. I decided to run the installation file for Microsoft Office 2010 as Administrator (because I forgot to in the first place), but it still didn't work. I then tried setting the permission on the folder to everyone, but it told me that I couldn't change the owner and that again my access was denied. (Yes, I had duplicate versions, but read on)
Whenever I click "OK" after changing the owner for the file, it tells me that it's "Unable to set new owner on 1033", because my access is denied.
When I uninstalled Microsoft Office 2003 and tried to reinstall Microsoft Office 2010, it still wouldn't let me get past that folder. In fact, I can't even reinstall Microsoft Office 2003 due to this issue.
