Downloading the file and installing it resulted in the same error message.

In this case the system is Windows 7 Home prem. 64-bit and the installation language is English.

The software installed is Office Home & Student 2010 English intl. 64-bit.

Language settings of the administrative account were as Finnish.  All settings were changed temporary as English (UK/GB).  Now the installation was successful.  Settings in the Region and Language were not be tested one at a time, but Formats, Location and Display Language were changed at once.
