arithmetic result exceeded 32 bits

We are also using Windows 7 X64 and a number of users have reported this issue. Initially we would kill the services, then run th repair update and this worked temporarily. However the problem returns. This began about 3 weeks ago. As we are a mix environment, I have checked for update 6632 and it is not running in our environment.
has anyone figured out which Win Update is doing this to the Win 7 environments?
