I did download the packer_windows_amd64.zip from https://circleci.com/gh/hashicorp/packer/19849#artifacts/containers/0
Extracted it in C:\Program Files\Packer and renamed the "previous" packer.exe there to packer1.exe . I am guessing this is right? Pretty new at this so..

Ah ! I opened a new PR (#8336) with some malformed snapshot data added in the tests too.

Please tell me if the new binary fixes it for you 🙂.

[stijnmaes1992]

Works fine now, tysm!
