Do you suppose there is a way to disable Electrum <3.3.4 from running entirely on a computer? There won't be much luck in Electrum itself but there should be some system administration tools that block specific programs from running on a computer.
There is pretty much no point to this... If you knew enough that Electrum 3.3.4 should not be run, you'd simply not use it... setting admin tools to block it is a waste of time.
And there is no way to force other peoples computers to not run it unless you're a System Admin in a corporate type environment... in which case, why would anyone want to run Bitcoin wallet software on a machine that they don't have full and exclusive (admin) access to?
