"System Update Required" to install ClickOnce app

I have been successfully deploying our application using ClickOnce, but
so far, only on XP workstations. I recently tried to deploy it to a
Windows 2000 workstation, running with SP4 and dotnet 2.0 framework.
The little window titled "Launching Application" comes up, then the
"Application Run - Security Warning" window prompts me to run the app
(because it isn't signed yet). I click "Run", and shortly afterwards I
get a window titled "System Update Required", and it contains the
message:

"Unable to install or run this application. This application requires
your system to be updated to Microsoft Windows Operating System version
5.1.2600.00.

Please contact your systems administrator"

I verified that the application doesn't really require Windows XP by
manually installing it and running it locally.

I also ran a quick verification of ClickOnce by creating a very simple,
small Windows forms app, published it, and successfully installed and
ran it on the same Win2K box.

Someone please help! I can't find anything about this error message
anywhere online. Thanks.
 
More digging into this led me to my application manifest (which is
generated by VS2005). It had this in it:

<dependency>
<dependentOS>
<osVersionInfo>
<os majorVersion="5" minorVersion="1" buildNumber="2600"
servicePackMajor="0" />
</osVersionInfo>
</dependentOS>
</dependency>

So, now the question is, why does think I need XP? My simple test
application published with a requirement of Windows version5, not 5.
 
hi,
Do you get any solution for your problem. i am also facing the same one.
I think the problem is due to using any other third party component or your own ocx control in your application.

i am also tested with small application.Its works properly in windows 2000.

How to register my ocx control in the end user's system, may found out the solution for this.

your opinion ..reply ..help me.
