If MetaDefender Kiosk doesn't start and you see the dialog below, it may be because the machine hosting MetaDefender Kiosk is too slow. (This can be for a number underlying of reasons, including underpowered CPU, not enough RAM, or slow hard disk).
To fix this issue, create the string registry key launch_delay_seconds in "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\OPSWAT\MD4M" and set this to any value greater than zero.
To set this registry key open the Regedit utility and follow the steps below:
Navigate to "HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\OPSWAT\MD4M"
Right-click and choose New > String Value
Name the new value launch_delay_seconds
Double click the newly assigned String and assign it a value greater than 0 (eg. 60) seconds
Restart MetaDefender Kiosk and MetaDefender Kiosk Rest service by opening an elevated command prompt and type the following commands:
net stop metadefenderSVC
net stop omdrest *
net start omdrest *
net start metadefenderSVC
If following these steps still does not resolve the issue, please log a ticket with OPSWAT Support
*omdrest service is only applicable to Kiosk version older than 4.4.0
