Tell me please, which folders and perhaps the registry keys need to removed in order to make a completely new clean install of the wallet?
OS - Windows 10
When I migrated from VoteCoin GUI v.1.1.2 to v.2.0.0 I just moved VoteCoin folder (path: ~\resources\app\VoteCoin) to the new one. This folder contains wallet.dat and blockchain. Also recommended to backup private keys to the separate drive
