well i am trying to import my private key from 2014 into the huntercore wallet but i get ' error -4 pruned chain cant rescan' or something similar. i thought i downloaded the entire chain?
You cannot used the prune chain for anything except if you are a brand new person and don't have an old wallet and just want to save time.
You have to download the new wallet and blockchain, there is a bootstrap link in the op.
Also check the properties on any desktop links after you delete the all in one. If you click on the same desktop link from the all in one you will cause the "new" download to not work properly.
