Error at initialization phase

[marmold]

After seting up $env:PACKER_PLUGIN_PATH with latest plugin bianary a following error appear:

Error: Failed to initialize build "hyperv-iso"

error initializing post-processor 'wim': Unknown post-processor wim



==> Wait completed after 0 seconds

==> Builds finished but no artifacts were created.

However, when binary is named strictly packer-plugin-wim.exe, packer is able to find the plugin. It seems that some strict versioning is hardcoded in the plugin.
