I was having a laptop running with Windows Vista RC1 64bit. I installed Office 2007 beta couple of months ago. Recently I upgraded my Vista to Vista x64 Ultimate RTM and now trying to install Office 2007 RTM. I downloaded this Office package from Microsoft download center. While doing this I remained unsuccessful with the Error Code 2203.
I saw few other discussions on this forum where they we need to uninstall the trial version completely from the system. I tried to do the same, went to Add and Remove program, but surprisingly I dint found any office program in the entire list. As a troubleshooting I tried to burn ISO to a new DVD, dint helped. I download the ISO again and burned it again on a new DVD, yet no help. I extracted the ISO to a folder and tried installing, yet no help. Tried checking the SHA-1 checksum and tried again, yet no help. Tried turning Off/On UAC, enabled the Administrator account, and many more things but none of them helped me yet. Still am getting the same error message.
The only thing left to do now is to Re-install entire Windows Vista again, I can do that but donít want to do unless I know it will solve the problem. Hence need some help from you all guys. Please suggest some working solution soon. Thank you.
