Okay, for what it is worth, I work in IT and have found a solution that works for "ME"
Your mileage may vary and please understand that I make NO promises that this will work for anyone else as well.
What worked for me was:
Download a file called "jarfix.exe" from https://johann.loefflmann.net/en/software/jarfix/index.html#Download (as ALWAYS scan the file you download with your favorite AV scanner before running) There are details about the file at this site if you are interested in reading them as well.
Double click/run the file AS AN ADMINISTRATOR
Double click on your "OpenRocket" icon, "Ta Da" (for me anyway)
The above pre-supposes that you have already verified that you have the newest version of JAVA installed as well.
Hope this helps others resolve this issue as well! For those that have posted other answers, Thanks for your help also!
