    Generally speaking COM isn't supported in App Service / Functions due to the sandbox that your code runs in

    An almost identical Q&A on this (and trying to access Excel) is here https://learn.microsoft.com/en-us/answers/questions/247908/how-to-register-microsoft-component-object-model-i

    App Service supports windows containers (as well as AKS), but as far as I know windows containers aren't supported yet by Functions. They are also not supported yet on Container Apps.

    So you could host an API in App Service on a windows container - this would give much more access to the guest OS and should unblock you here
