You can also try the folowing: Install acrobat_language.x.exe untill you get the wizard. Then you click on cancel. The will find the MSI package in you %systemroot%\cache\acrobat x folder. Then you can use the folowing switch: msiexec /i "S:\Acrobat\Reader6\Adobe Reader 6.0.msi" /qb-! This will install acrobat reader silently without cancel button..... Good Luck!
