please tell me more, how should I update electrum to new versions, uninstall older first or simply install it over? with second option electrum create new other .exe file to run program.
I think install much better to uninstall first but you should have the private key of your wallet first or even the seeds backup before you install a new version of electrum so that you'll not experience any issue..
For me my electrum wallet still not upgraded. but its still can be use without any issue..
