There is no Windows wallet as of yet, so i installed the Linux BTCP wallet from github:
https://github.com/BTCPrivate/BitcoinPrivateOne of the last steps is this:
# Fetch Zcash ceremony keys
./btcputil/fetch-params.sh
This script will fetch the Bitcoin Private (and Zcash) zkSNARK parameters, and verify
their integrity with sha256sum. These parameters are identical to those for
both Zclassic and Zcash.
If they already exist locally, it will exit now and do nothing else.

So that does not work...
I have ZCL installed but I'm not sure those keys are identical.
