Problem with HttpDownloader by Kent Boogaart

[Mateusz [PEYN] Adamus]

Hi everyone

Lately I implemented Updater Block v.2.0 into my app but today I found
out that it's not working on Win98. I searched the web and found the
HttpDownloader made by Kent Boogaart.

I have my app compiled and it worked fine with the BITS (on WinXP). I
put the HttpDownloader.dll into my apps directory, modified the
app.config and updaterconfiguration.config as shown in readme.html and
fired all up.

Application downloaded the manifest files but when I give it a "go
ahead" for downloading updates I get this exception:
Microsoft.ApplicationBlocks.Updater.ApplicationUpdaterException:

The
Downloader Manager is unable to locate and/or create the downloader
instance. ---> System.NullReferenceException: Object reference not
set to an instance of an object.

selectedManifests, TimeSpan maxWaitTime)

Has anyone had the same problem? I've seen that over a 1k people
downloaded it so I guess I can't be the only one who came accross this
exception.

I'm developing in Delphi 2005 - maybe this is problem?
Maybe I have to add reference in project for this dll?
I took code activating the downloader from MS examples (InProx exactly)
- maybe I have to modify it in some way?

Big TIA

Have you made the necessary changes to the manifest.xml file? You need
to specify what downloader to use. You should include the line:
<downloader name="HttpDownloader" /> in the manifest. If the downloader
name is not specified BITS will be used by default.

Hope that helps.
