Found the file in the path you indicated, but not being very practical (I made some mistakes in editing) and the gadget no longer worked, at least I had made a backup and it returned as before, that is to 0.
The normal location for skins, assuming you are using a normal install instead of a portable install, is:
C:\Users\<username>\Documents\Rainmeter\Skins
You will see the Gadgets folder here, and inside that you will see all the individual skin folders, including the @Resources folder.
I prefer, for now, to downgrade to 7.8.0, since I am about to buy a new PC and surely with that it will work.
Thank you all the same.
