The link in my post is the same KB you posted and does not apply here. The 3010 is not occurring on any of the files mentioned in that article. The "in use" files are python.exe and python27.dll and aren't loaded into memory until the install gets to the point of "Vmware python components", at which point the vmware-python.msi or some sub-process of it loads the files into memory and the MSI then trips over itself detecting the files that it just loaded as being in use.
Let me stress, I am not looking for help here. I KNOW what caused the problem and in my case it is definitive. This is more or less a PSA for anyone else that runs into this problem.
