Jupyter Notebook tile not on opening Navigator screen

I expect I have just made a mistake. I have multiple Anaconda entries on my disk under \users\user folder. Will it hurt to delete ALL of the installations and start fresh with just one Anaconda installation? It seems all of my .ipynb and other project files would be accessible from the new Anaconda and hopefully it would now show Jupyter Notebook. Jupyter Labs has always been there. Thanks.
