Unspecified automation error when launching Excel with the BAM add-in enabled
Right when I needed to make a change in a hurry to a BAM Activity, I started throwing an "Unspecified Automation Error" on two of my three development machines when launching Excel with the BAM add-in. Excel would launch, throw the error, then launch a VBA window. While I got my change in on the third (unaffected) machine, I finally got some time to circle back to this. From the post below, a recent patch caused this issue, but at least it's understood and only requires re-registering MSCOMCTL.OCX.
