It is something I am working on in another area, Mike. I have an external HD, with most of my Software executives, in a folder, on it. Many of these can be run normally, but there are at least half a dozen which, with Windows 10, come up with the message that the path does not exist. If I copy them to the internal - which, oddly, I can do without fuss, then they will run. I logged this with MS Feedback and on the technet forums, but have had no return feedback from anywhere. Perhaps it is merely a missing dll, which will come with a future update. There are Quite a few missing at the moment, which may be responsible.
