Hi rcrespos,
Please try downloading the Acrobat X pro from this Link and check whether you are able to install it or not. If yes that means the files are corrupted in the CS6 suite abd may require you to redownload the suite.
To download Acrobat X pro please use this link http://helpx.adobe.com/acrobat/kb/acrobat-downloads.html
please let us know if it helps.
