Why doesn’t my MetaDefender Kiosk start?
This article applies to all MetaDefender Kiosk V4 releases deployed on Windows systems.
If your MetaDefender Kiosk fails to start, and you see the error message pictured below, it may be due to performance and slow speed issues on the machine hosting the Kiosk.

There are a variety of possible reasons for this, ranging from an underpowered CPU and low RAM, to a slow hard disk and numerous possible system errors.
To fix this issue, you will need to create a string registry key entitled launch_delay_seconds in the folder at path: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\OPSWAT\MD4M and you will need to set it to any value greater than zero.
To set this registry key, open the Windows Regedit utility before following the steps below:

- Navigate to the folder at \HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\OPSWAT\MD4M, as illustrated below.

- Right-click, then choose New>String Value from the dropdown menu, shown in the screenshot below.

- Name the new value launch_delay_seconds

- Double click the newly assigned String and assign it a value greater than 0 (eg. 60) seconds

Open an elevated command prompt (as Administrator) and enter the following commands in order to restart MetaDefender Kiosk and MetaDefender Kiosk REST service:
net stop metadefenderSVC
net stop omdrest *
net start omdrest *
net start metadefenderSVC
*omdrest Service only applies to Metadefender Kiosk versions older and including 4.4.0.
