My issue I resolved - the missing file is a Microsoft file from the Visual C++ redistributable. Only thousands of people have gotten this error message over a period of years with different software programs. What puzzles me is that this JMP installation has worked fine for the past year and now suddenly the file is missing. How does that happen?
The only thing I would note is that I postponed the latest Windows 11 update - because I am teaching this short course and I've had issues in the past with Microsoft update breaking things. Is it possible that by not updating, the file JMP needs went missing?
One in a growing list of issues I have with Microsoft. They are the most unresponsive and irresponsible companies I have any experience with. Class action lawsuits are in their future! But really, if anybody has any insight, I am very interested in understanding what happened.
