Anvil.http doesn't work on windows?

[szkrd]

After anvil install anvil.http I want to run the anvil host, but this is what I get:

Installation of 'anvil.http' completed successfully.

c:\szabi\dev\www\sandbox\anvil\browsertest>anvil --host --ci --browser

I have VS C++ Express, so socket.io does build, though I have two v8 warnings (but I doubt that's the problem). Do I have to set up something in build.json?

Sorry, I guess I shoule move this to the main anvil issue list.
