Impossible to generate guest card DLL hunerf.dll for operation. - Keycard.

while generating a key from the system we need to check if the SDK or DLL of the Hune Door lock is available in the Integration folder or not.

1. It can be possible that SDK file of the Door lock software has been removed from the folder. There can be many reasons as most of the SDK files Antivirus are considering it as a threat and that might be removed.

2. We can ask hoteliers for the Hune Lock SDK, So once we received SDK from the hoteliers we can place it in the Folder where integration files were kept.
3. We can run the Host file again as an administrator and check if it's generating or not. This will resolve the above concern and hoteliers should be able to generate cards from System. This will resolve the concern.
