Because of no cfn-signal SUCCESS replies, the stack is getting timed-out

I had to work around this by reverting cfn-bootstrap to older version (taken from previously working AMI)


## This should be executed before running `cfn-init`
Remove-Item "C:\Program Files\Amazon\cfn-bootstrap\*"  -Force
Read-S3Object -BucketName "<YOUR BUCKET HERE>" -Key "cfn-bootstrap.zip" -File "C:\Windows\temp\cfn-bootstrap.zip"
Add-Type -AssemblyName System.IO.Compression.FileSystem
[System.IO.Compression.ZipFile]::ExtractToDirectory("C:\Windows\temp\cfn-bootstrap.zip", "C:\Program Files\Amazon\cfn-bootstrap\")

Thanks for your notice! This repo actually covers the open source cloudformation command line tool, which is separate from the cfn-bootstrap package that you are referring to.

This may be helpful https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/releasehistory-aws-cfn-bootstrap.html
