Annoying out of nowhere my Heroku toolbelt always attempts to update anytime I make a Heroku command. This wouldn't be so bad if it actually did update but no matter what permissions I give to the desination folder or CMD I get an Access is Denied error.
This makes executing commands on with Heroku extremely time consuming because it always re-downloads the update and fail in setting up Node before executing the command I ask it to.
Below is an example of what the error looks like.
Installing Heroku Toolbelt v4... done.

I fixed this by deleting the folders Username/.heroku , and Username/AppData/Local/heroku, (Replace "Username" with your username) then run heroku login results in a successful install of node, after that it seems to work smoothly (so far). Probably deleting the first folder isn't necessary -- but that's what I did in any case.
Good luck
