- Temporarily disable any antivirus programs you have running when you attempt to install Atom
- If #1 doesn’t work and you see the text “PathTooLong” in the output, then you’re running into a known Issue that we’re tracking. While we work on the longer term solution, there is a workaround.
If neither of the above works, please file an Issue on https://github.com/atom/atom and include in your post the contents of
%USERPROFILE%\appdata\local\atom\squirrelsetup.log. If it is too large, you can use https://gist.github.com to post it and then include a link.
