Reinstalling Bundled Version of Acrobat 8 Std

Hello,

I was forced to reinstall Windows on a client PC because of a virus infection and now I am having trouble reinstalling Acrobat. The software came preinstalled from Dell and I have the package that came with it. However, when I try to install the software, the serial number doesn't work. It tells me that the serial number is already installed on the maximum number of PCs.

The problem is that with preinstalled Acrobat software, there is no way to de-activate the software. That option is not available under Help > Activation.

Is there a way to reinstall the bundled version of Acrobat?

Thanks for the help.
