+ 0 Votes Known Issue BFilmFan 5 years ago This is a known issue. You need to download and run the Microsoft Windows Installer Cleanup Utility. See http://support.microsoft.com/kb/290301. + 0 Votes Doesn't Work! sam.mereki 5 years ago Sorry but I downloaded, installed and run the program but it did not work. I hope you have a better solution? Thanks anyway. + 0 Votes Feed it the disk and let it complete... ThumbsUp2 5 years ago You've probably turned on an option that wasn't originally installed (ie, set to install on first use). It wants the disk so it can complete the install.You can avoid this if you do a complete install instead of the normal (recommended) install. + 0 Votes Not Yet Solved. sam.mereki 5 years ago I uninstalled and reinstalled Microsoft Office 2007 Enterprise Edition but this this time a complete installation and not standard (recommended one)with all features turned on. The problem however continues. I am confused. Thanks for your contribution anyway. + 0 Votes Feed it the disk.... ThumbsUp2 5 years ago There is a registry entry somewhere which thinks the option still needs to be installed. Just feed it the disk when it asks and let it complete the install. That will make it go away.But, if you want, you can uninstall and then run the utility which Microsoft offers as a download to completely remove all traces of Office from the system. After that is run, you can perform the complete install once again. Sorry, I can't locate the download right now at the MS web site. But, I know there is one. + 0 Votes Tried that, Sorry. sam.mereki 5 years ago I have tried that using Revo Uninstaller which can be downloaded from http://www.revouninstaller.com/revosetup.exe - still no luck after complete re-installation of Microsoft Office Enterprise Edition. I'm sorry. + 0 Votes Solved sam.mereki 5 years ago Friends:I have found the problem at last. It was a faulty DVD drive. I replaced DVD drive and after complete installation, the problem did come up again. Thanks for your time and contributions all the same. I am closing this issue.
