Hi, my first post on this site. I've been trying to speed up my laptop by getting ridding of programs I don't use and have inadvertently deleted Microsoft Office Professional 2003 edition. Obviously all my Excel and Word packages stopped working. I've now done a sytem restore and, whilst the Microsoft programs "appear" to be OK I can't actualy open any of them. A pop up box appears saying "Windows Installer" preparing for installation. This may be related to an earlier problem whereby I did a microsoft update (and have had problems ever since). You can probably gather I'm not that hot with the technical stuff. Hope someone can help
