so if I just replace the primecoin-qt.exe and the daemon on this windows machine, what will happen with the coins that are already on this machine? Or is it best to send these coins to another account before installing this release on this machine?
We need good Wiki or a FAQ. Same questions been asked over and over again, and you can't point people anywhere.
Your coins are tied to your private key(s), which is in wallet.dat file. That file is located in totally separate directory from your Primecoin client, and any re-installation has no effect on it.
on a windows machine, where is this wallet.dat file stored? Im not finding it.
