I installed the Heroku toolbox on my win 7 machine. The next step to setting it up was to use the command line to login.

Start at the command line and type in “heroku login”. I entered my email address and password associated with the account. Came back with, “Could not find an existing public key. Would you like to generate one? [Yn]”. I typed y and hit enter, and I got the following:

“Could not generate key:  ‘ssh-keygin’ is not  recognized as an internal or external command, operable program or batch file.”

Searched the web and found that installing Git from this site http://git-scm.com/download/win made it possible.

After downloading and installing Git, I went to C:\program files(x86)\git\ and clicked on the “Get Bash” short cut. A command line prompt opened. I typed in the same thing as before, “heroku login”. It asked for email and password. Asked me to generate a key[Yn], I typed y, hit enter and everything worked this time.
