Hi Jon,
As mentioned and just to be clear, this is not SP2, it is a hotfix that will most likely be included with SP2.
Issue that this hotfix package fixes
Assume that you open a database that contains Visual Basic for Application (VBA) code. In this situation, Microsoft Access 2010 may crash when you change the database. Note This issue occurs after you apply Microsoft Office 2010 Service Pack 1 (SP1).
The paragraph above, which is also in the article, simply states what causes the issue to begin with.
The prerequisites section is what you need to look at to see what needs to be installed before installing the hotfix.
Prerequisites
To apply this hotfix package, you must
have Microsoft Office 2010.
The files you are putting on your machine will have a higher build then the files in SP1 and should be left alone when SP1 is installed.
To test, this, simply install the hotfix on a machine without SP1 and look at the version number of VBE7.dll on your machine.
Then install SP1 and once again take a look at the VBE7.dll file on your machine.
