The ZClassic team has been hard at work at porting over over the wallet to be Windows x64 compatible. We are happy to be releasing an experimental build of our work in progress. This build will allow you to send and receive t-address transactions and also receive z-address transactions.
We're still hard at work on porting over some other portions of the code and you can expect us to release a new version very soon!
