            Status: UNCONFIRMED
          Severity: normal

Screenshot of the actual error along terminal output without debug trace.

When using built-in winhttp, trying to launch Final Fantasy XIV - A Realm
Reborn fails at the very start of the launch process, where the launcher sends
an HTTP request to check if a newer version of the launcher is available.

When no new version is available, the server replies with status code 204: No
Content.

However, builtin wine seems to misreport 4294967295 (2^32-1) bytes of available
data in the response, as shown by this tiny snippet of trace:

When using native winhttp, no calls to WinHttpReadData are made.
