Hello,
I have old Microcoin wallet.dat but can't find old wallet instalator.
Is there any chance to change old Microcoin to new?
Regards.
Just keep the wallet.dat safe and download the old wallets from microcoin homepage.
From microCoin homepage:
http://microcoin.alcurex.info/wallets-and-toolsit is very slow but have patience, once you load the wallet just send them to alcurex.
