cannot install acrobat x standard on vista

We cannot install acrobat x standard on one of the Vista. It shows it fails to fulfill the minimum requirement.

The computer should meet all minimum requirement. We have also tried to install on another computer with same spec and it is ok.

The details of the computer are as following:

Windows Vista home basic

service pack 1

Internet explorer 8

Intel core 2 duo E7500 2.93Ghz

4Gh ram

32 bit

Are there any other areas we should consider and check for?
