How to resolve "git did not exit cleanly (exit code 128)" error on TortoiseGit?

If you're running windows 7:

I was trying to decide the best way to do this securely, but the lazy way is :

1. right-click the parent folder
2. click the "properties" button
3. click the "security" tab
4. click the "edit" button
5. click the group that starts with "Users"
6. click the checkbox that says "full control"
7. click all the OK's to close the dialogs.

I realize this might circumvent windows "security" features, but it gets the job done.

for me I simply had to add configure my git username and email with the following commands:

git config --global user.email "[email protected]"
git config --global user.name "Your Name"

It's probably because your SSH key has been removed/revoked. Make a new one and add it to your GitHub account.
