My user is not able to start neither Excel neither Word. When starting Excel, Windows Installer start and require Office 2000 Premium. Locate it thru our Network and it give me an error about invalid Windows Installer. Tried to reinstall Office but I got the message from Windows Installer: "Impossible to open this package. Check if it exist and you are authorized to access it, or check if this package is a valid Windows Installer" (or something like that, french translation...). Try to unstall Office but get the same pathern. My questions are why this and how I can fix it.
