Then it upgraded to Win 8.1. Then I upgraded it to Win 10. Then I upgraded it to Threshold 2. It gets regular automatic updates also, like the one last night to build 10586.17. That's the history. When she tried a python script today, it failed, with an error saying that MSVCR100.dll was missing. After a few false starts, like being surprised that the error happened when it worked yesterday, and that there was an MSVCR100.dll in %windir%\system32, doing a search for all MSVCR100.dll on her machine discovered quite a few in various application directories, but then also one in \windows.old\WINDOWS\SysWOW64, the light-bulb blinked on, I copied that one to the \python33 directory, and everything works. Why M$ chose to delete MSVCR100.dll from %windir%\SysWOW64 in the recent update is a mystery, however. So this is just a data point and warning and solution, not really an expectation that anyone will be able to explain M$. Glenn
