installation faillelure

when I try to install Adobe reader 9.* at 98% there is a message :

''The installationprogram discovered that you have allready a more functional product installed. The installationprogram will be stopped.''

But now I can`t open PDF files. Who knows what`s wrong and who has a sollution?

Do you have a copy of Acrobat or Reader on your computer? If so remove both Acrobat and Reader and then install just one of the programs. If necessary you may have to use the Microsoft Installer Cleanup tool to remove all traces of both programs.
