Studio Takes Longer than One Minute to Launch

If you notice that launching Livestream Studio suddenly goes from taking about 20 seconds to launch to over a minute, or the settings menu takes a long time to open, it may be due to a Windows feature called Fault Tolerant Heap (FTH).

In summary, FTH monitors for software crashes and attempts to mitigate future crashes. Microsoft provides a detailed explanation of FTH, including how to check what applications (e.g. Studio) are FTH enabled.


If you have experienced Studio crashing in the past, this feature may be active and causing slowness when launching Studio or opening the Settings menu. Our testing has shown that clearing the FTH cache can resolve this.

In order to do this, you must be using Windows as an Administrator and Studio must be closed.

Open Terminal as an administrator. Run the following command from an elevated command prompt


<p>Rundll32.exe fthsvc.dll,FthSysprepSpecialize</p>
Click to copy

Running this command will clear all FTH applications, so applications that are currently functioning properly may begin to crash again after running this command.

After the command runs, restart Windows to apply the setting. After restarting, Studio should launch within the normal timeframe (20 seconds to one minute).
