I was trying to undestand which exactly Blockchain we can download from you:
old h2 version
It's good to add in the site which exactly database we are going to download and with which wallet is compatible.
because some jerks manually flag the mining software as malware and Microsoft heuristics (and some others) don't understand the wallet technology and need to look up the source code. It interferes with wallet installation shortcuts for some reason. I prevent the issue by disabling cloud based protection however the wallet and miner should still be there and you can navigate to it with windows explorer. Perhaps manually create icons from the wallet directory. manually submitting suspicious code flags applications as unsafe until proven safe but personally no wallet has caused a problem for me since recent times.
