I have ES 7.10.2 installed as a service in W10. Looking at some very cursory notes I seem to have made, I installed this by going
...\bin>elasticsearch-service.bat install
So I just downloaded the .zip for 7.16.3 (please don't ask why I don't yet want to move to 8!).
I stopped the existing 7.10.2 service, which is called "elasticsearch-service-x64"
In the unzipped 7.16.3 directory I went
...\bin> elasticsearch-service.bat installI get a screen saying "do you want to do this as admin" --> Yes
I get the following failure:

Failed installing 'elasticsearch-service-x64' service
yup, NOTHING ELSE. Spectacularly informative. To be fair, there may be some log output somewhere... But I have obviously have no idea where I might find that.
In a way I am not surprised that this failed to be installed, as there is already an existing service called "elasticsearch-service-x64", and just because it is stopped this wouldn't stop installing a new one with the same name being a problem. Can we install ES with a custom name??? (such as "elasticsearch-service-7.16.3"? Oh how helpful that might be).
But I am EXTREMELY nervous about, for example, uninstalling/deleting the present ES service 7.10.2, which does at least work. I am far from convinced that re-installing it would be trivial.
This time I intend to make many many more notes.
Has anyone had this experience? What do I do?
