I'm trying to unlock my wallet in Windows, but I'm having this problem.
C:\Program Files (x86)\PPCoin\daemon>ppcoind walletpassphrase (password) 6000 true
error: You must set rpcpassword= in the configuration file:
C:\...\AppData\Roaming\PPCoin\ppcoin.conf
If the file does not exist, create it with owner-readable-only file permissions.
I have made the file using the sample from github
