FitBit OS Simulator: Simulator failed to start

[VTW]

I've installed the Simulator. When I launch it, it starts loading, but eventually gives me the message "Dang. Simulator failed to start". I've looked in the log in `(...)\AppData\Roaming\Fitbit OS Simulator\logs\main.log`, which gives me the following message:

[error] Simulator hosts failed to start: MethodCallTimeout: No response received for RPC call to 'initialize'

Tried all things already suggested on the forum. 

• Reinstall simulator
• Delete folder "(...)\AppData\Roaming\Fitbit OS Simulator"

D'oh! Windows Update needed a restart. Worked after that... -.-'
