There's a possibility that your game is not booting due to a false positive from your anti-virus software. In order to avoid this, please add the following files and folders to your anti-virus and firewall exclusion lists. If you already have them registered, please remove them from the list and then re-add them.
- StreetFighter6ClosedBeta.exe (Default folder C:\Program Files (x86)\Steam\steamapps\common\Street Fighter 6 - Closed Beta)
- Steam.exe (Default folder C:\Program Files (x86)\Steam)
- Steam AppData (Default folder C:\Users\%USERNAME%\AppData\Local\Steam)
For instructions on how to update your exclusion list, please refer to your anti-virus software's manual.
