Hello,

you'll have to attach to the sub-installer from "C:\windows\temp\SITxxxx\" to
see something meaningful otherwise Microsoft's own JIT debugger (watson) ought
to be called. Ironically the JIT debugger DW20.exe isn't present at this point
because the package (dw20shared.msi) is to be downloaded first using winhttp
;-)

status -> WINHTTP_CALLBACK_STATUS_SENDREQUEST_COMPLETE

It seems the callback looks at the context parameter and relies on it to
contain something meaningful when called.

dlls/winhttp/request.c:send_request() (task_send_request) already gets a
context passed in (initially from WinHttpSendRequest).

Using that context gets the installer a little further only to stumble into
next winhttp bug.

To work around you might try native winhttp.
