I get an "Unknown Publisher" error message when trying to install Acrobat X. Windows XP sp3

[Guest]

I am trying to install Acrobat X reader on Windows XP sp3 operating system and get a "Unknown Publisher" error and it will not install. How do I get around this?

I think you are getting this error while installing Adobe Reader X instead of Acrobat X. If so, you might try installing the latest update for reader X.
