I watched Cryptomined youtube video explaining how to get and use the gui wallet and that the download is zcash4win1.0.5 msi and is suppose to prove the sha56 key but i believe its you upgraded now to zcash4win 1.0.6 msi and i am not getting the same proving key? Is this because it is a upgraded version?
As I mention in the other thread, you can delete the proving key and it will be redownloaded…it does NOT change from release to release, it would only change if there was a hard fork that involved another trusted setup and all zcash nodes would have to download a new one, which is not likely to happen (hopefully!) any time soon, if ever.
