"System Update Required" to install ClickOnce app

[gkustas]

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.
