> [@GaurangTandon](#): > > Anyway to revert this to get things working properly? Unfortunately, if there is a way to “undo” or “rollback” I don’t know how. I had a few false starts, each time getting a bit further. But what I did was uninstall GitHub, VirtualBox, and Vagrant paying more attention to things I might have missed before and trying things a bit different. (and yes, upgrading gems was one thing I tried) The first “successful” attempt ran painfully slow. I believe it was because I installed everything directly under C and Windows had a security / privilege problem with that. At least I think that was why I had “sharing” problems. That, and I was opening the shell from the GitHub GUI Then I upgraded to Windows 10 and everything broke, forcing me to try again. This last time, which knock wood has been running well, I: - installed GitHub - used all defaults - installed VirtualBox - used all defaults - installed Vagrant - used all defaults - instead of putting my “work” under C I put it under C:/users/[me]/documents/virtualworkspace/discourse - I open the shell from the Start menu - GitHub - Git Shell - I don’t touch the GitHub or VirtualBox GUI It takes a bit more effort cd’ing to the work folder, but Windows hasn’t complained yet. --- _[View the full topic](https://meta.discourse.org/t/cannot-view-0-0-0-0-3000-in-browser-and-localhost-4000-gives-error/41357)._
