AWS CloudFormation Template for customized windows AMI not running cfn-init and not creating the related files

Question

Below is my template snippet in which Windows Custom AMI is used to create the server. Here cfn-init.exe is not getting executed even if I have given it in the userdata block. As a result no files are gettting created in my server. Please help.

Thanks in Advance.
