This can also be caused by your antivirus software preventing you from writing the LaunchJMRI.exe file because it is a new version and that antivirus software doesn't yet trust it.
If you know how to do so, tell your antivirus software to "install anyway". That helps build its reputation for others. Otherwise, temporarily disable your antivirus software while you install JMRI.
