Here is how the situation arised.

I have on my machine a licensed copy of VS 2005 and VS 2008. 

I then installed Silverlight 2 Beta Tools for VS 2008 , Windows Live Tools for Microsoft Visual Studio, Virtual Earth Map Control SDK 6.1 and MapPointWebServiceSDK v4.5 to play around with Virtual Earth development.

Later on I installed a licensed copy of Expression Studio 2.

I started playing with Silverlight application. I have ran a simple page with silverlight controls. From the VS 2008, I wanted to be able to edit the xaml page by right clicking on it from VS and then it will open in Expression Blend 2. Unfortunately it didn't open because my example application is already Silverlight 2 Beta application.

And so I decided to install Blend SP1. But before that I first installed the  Service Pack Preparation tool  then the VS 2008 SP1. 

I opened my sample silverlight application but it gives me an error. Something like "unable to locate plugins", something like that. And so I install the link that was given in the message box. I think it is the  Silverlight 2 Beta 2 tools for VS 2008.

After I installed the patch I was able to open my sample application. And here my problem begins. Whenever I tried to run the application, the browser always ask me to download the Silverlight plugins. I downloaded and installed it but still I can not run my application. I can browse other Silverlight page on the internet but I can not run my application. My browser always ask for Silverlight plugins.  What I am missing here?

Any help will be appreciated. Thanks.

What mime type or MinVersion value is your test page using?

Beta 2 sites should use MIME type of application/x-silveright-2-b2 and MinVersion 2.0.30523

RC sites should use MIME type of application/x-silveright-2 and MinVersion 2.0.30923

My first example application which has MinVersion of 2.0.30523 no longer runs. When I created a new application which now has MinVersion of 2.0.30923 still does not run. Browser ask for Silverlight plugin to be downloaded when I tried to run both of my applications.  

What would be the problem here? What's wrong with the sequence of my installation? How will I fix this?

Thanks!

My issue is very similiar.  Except it started when I couldn't run my SL project in debug mode.  I corrected that by installing the developer version of the SL plugin.  That worked as far arunning the project in debug mode, but the browser only shows me the "Install Silverlight" image. 

After installing, I have restarted my browser, restarted my machine, uninstalled the plugin, reinstalled it, uninstalled the developer tools, reinstalled them and the plugin, but nothing works.  Any Silverlight site I go to, the site asks me to install silverlight. After the install, it claims success and to refresh the browser, but no love.

There are too many people with this problem for there not to be a definitive solution.  Anyone have a working solution to this issue?

Hi Mastereuo,

It is a little weird.  To make things easier,  we suggest that you'd better remove all the Silverlight related comphonents away, then reinstall them.  Please take a look at my reply on this thread.   By the way, the latest available version is Silverlight 2 RC0, you can upgrade to it by following this link.

Best regards,

I also have a similar problem

I installed RC0 on my development machine to test my SL application and that runs fine locally in FF and IE BUT.......

When I try an access my deployed SL I get both FF and IE asking to install SL again

The deployed app  has a MinimumVersion="2.0.30523" set

My dev machine  now has 2.0.30923.0 (=RC0)

If I try and install SL on my dev machine it says I have a newer version.

 Any suggestions ?

 Mike

Thanks

Mike

somehow, since rc0, silverlight only tends to work in IE. Not sure why but firefox refuses any Silverlight page (ie, none of the showcase entries work on firefox yet all of them work in IE). Local SL apps do work in both browsers though...

The page just stays empty in FF, no errors whatsoever...

Hi ShadowOfTheBreast,

If the website that you are visiting is using Silverlight 1,  the prompt will show even though we have installed Silverlight 2.   Currently,  Silverlight 2 RTW is released.

Hi ShadowOfTheBeast,

I'm afraid that the answer is yes.   Would you please give me the link?   I will check it to see whether it is using Silverlight 1.   Most of the websites, which are using Silverlight 1, have been migrated to Silverlight 2. 

Best regards,

Jonathan

Hi ShadowOfTheBeast,

Please check its silverlight version by going through the page, which is hosted the Silverlight plugin.  For example,

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
        <div  style="height:100%;">
            <asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/DataGridAccess.xap" MinimumVersion="2.0.31005.0" Width="100%" Height="100%" />
        </div>

It is a sample for Silverlight 2 RTW.  Some of the samples are not migrated to the latest platform.  Thanks for understanding.

Best regards,

Jonathan

Hi Jonathan, here is the Link

http://silverlight.net/GetStarted/

the Scot Guthrie '  8 part tutorial, I can even get past part 2 of it, due to this issue....do you mean the Test page? that host's the SilverLight App the Html and the asp pages as there are 2 pages(Html and aspnet generated)  to host the Silverlight app from this tutorial.

This above all: to thine own self be true.

I am having the exact same problem.  I have developed the app, I am able to run it by launching the IDE, but when I visit the deployed site, I just get the install link.

 Any known cure?

Hi Jonathan,

Ok i have looked at my test aspnet page that hists the SliverLight application and this the what i have:

<%@ Register Assembly="System.Web.Silverlight" Namespace="System.Web.UI.SilverlightControls"

TagPrefix="asp" %>

<html xmlns="http://www.w3.org/1999/xhtml" style="height:100%;">

<head runat="server">

</head>

<body style="height:100%;margin:0;">

<form id="form1" runat="server" style="height:100%;">

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

<div style="height:100%;">

<asp:Silverlight ID="Xaml1" runat="server" Source="~/ClientBin/DiggSample.xap" MinimumVersion="2.0.31005.0" Width="100%" Height="100%" />

</div>

</body>

</html>

Hence the version is  silverLight 2, so what do i need  to do resolve this?

Hi umm what do you mean you are able to run it "by Launching the IDE, do you mean when you run the application by hitting F5 the browser displays your app correctly?

This above all: to thine own self be true.

William shakespeare, Hamlet

Hi,

at least it seems that you have a deployed version that does not work but a local version that does is that what you are saying ? if it is i dont even get that far....my local version does not ven work i just get the stupid blank page with "install SilverLight" logo on it :

This above all: to thine own self be true.

I run the app by launching from the IDE in debug mode. Just clicking run while in debug. 

I think I've solved my problem.  The test site actually wasn't redeployed yesterday.  This means that the silverlight components in the bin directory are still beta 2 and are generating the beta 2 script code when the site is accessed.

I was thinking it was something on my dev box so I uninstalled the sdk and vs2008 tools.  Once I get them reinstalled, I'll republish and test this out.  I'm gonna go out on a limb though and figure it'll fix my problem though.

Hi thanks for that please let me know if it works, as i have not tried deploying it...just running it from the IDE,still the same though 

This above all: to thine own self be true.

William shakespeare, Hamlet

I have checked and you are right! i looked in the bin and the dll version is of the application is version 1.0! and i have Silverlight 2.0 installed, so i think one way is to install SilverLight 1.0 until the samples have been migrated to Version 2.0 who knows when that will happen....it funny there is already a download for silverlight 2 but the sample apps are still in Silverlight 1....just greeeeaaaaaat!

This above all: to thine own self be true.

William shakespeare, Hamlet

So that did fix it for me.  Just needed to redeploy the site.  Guess I'll wear the dunce cap for the rest of the week. 

Hi could you please give me a step- by - step account of how you did it?

...cos at this point i might have to wear the dunce cap for 2 weeks!

This above all: to thine own self be true.

 It's already a late reply. I've been busy for the past months.

 Jonathan Shen – MSFT suggestion made my SL App works now. I uninstall all SL related components and then reinstall all over again. But I now use the SL Tools final release not the Beta one.
