A number of XSplit users have been reporting issues of their stream not going as live when streaming to Twitch or have been unable to start recording. The cause of this issue is unregistered .dll files in Windows OS files. To fix, follow the following steps:

1. Download regfix.bat and place anywhere on your hard drive
2. Right click and select “run as administrator”
3. If smart screen pop’s up for protection, then press “more info” and select  “run anyway”
4. Windows will now run a repair to check for replaced files

Hopefully this will resolve the issue, for any other issues with Xsplit or if it persists please visit the XSplit Support Panel.
