Here are the preliminary facts:
- Windows XP, including latest updates
- Office 2003, including latest updates
Error messages encountered:
- "Product: Microsoft Office (Version) -- Error 1704. An installation for Microsoft Office (Version) is currently suspended. You must undo the changes made by that installation to continue. Do you want to undo those changes?"
- After clicking Yes and waiting for awhile, this message comes up: "Error 1712.One or more of the files required to restore your computer to its previous state could not be found. Restoration will not be possible."
The real problem here was that the laptop that was running the Office 2007 installer to upgrade Office 2003 and the notebook ran out of juice (wrong power supply was used, which meant that it was running solely off battery). The installation process was interrupted and left in an unusable state. Office was no longer listed in the list for Add/Remove Programs. Running the Office 2007 installation did not recognize that we still wanted to upgrade, which meant that it didn't recognize a usable version of Office on the machine.
The Fix:
This involves a registry hack. As usual, editing the registry incorrectly could cause Windows to function incorrectly. Please make sure to backup your registry settings before making any changes. Ultimately, use these instructions at your own risk.
The registry key is:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Installer\InProgress
I deleted the key entirely, rebooted, then ran the Office 2007 installation again. If I had to go back, I would go in and delete all the files related to Office in Program Files and any installation files to create a clean environment for the new Office 2007 installation.
Nevertheless, this worked for me. Hope this helps someone else.
