I know I can disable the Silverlight add-on using the Manage Add-ons dialog, but what other settings would cause Silverlight to not function and display the Install link, if the correct version of Silverlight is actually installed on the computer?
Silverlight applications do not display (they show the Install link) in Internet Explorer 7 on a single client's computer under one administrative user's account. They display in FireFox and Chrome on the same computer. They work for other users in Internet Explorer on the same computer. The add-on is enabled. It shows the same symptoms as if you disable the Silverlight add-on. What else could cause this?
Is Javascript enabled in IE? Is the site hosting the application in the Restricted Sites zone?

We are trying to integrate Silverlight components in Outlook task panel which is developed by Outlook Javascript API. However when mailapp(task panel) loaded, it appears error and it prompts the Silverlight addin failed to run and please check security settings in “Internet Options”. I also tried adding website URL into IE trusted sites list, but this error remains. But I also notice that it works fine in IE browsers.
I know the mailapp (task panel) initials a web browser (IE kernel) in embedded mode. But I really want to confirm whether Silverlight is supported or NOT in MailApp？ If it's supported, how should I do?
Anyone gives me the right answer will save my life. Thanks in advance.
It prompts security settings conflicted in MailApp
But it works fine in a separate IE browser
First my apologies if I failed to find an answer searching - I tried a variety of search topics but none that were directly related.
I have a Lightswitch app deployed and working fine, running on IIS 7 and Windows Server 2008. It is an internal intranet app only.
I am using only FORMS AUTHENTICATION, all others are disabled.
The app works fine for MOST windows users.
However, some windows users get nothing but a blank screen - no login, no "loading..." and no silverlight "98%" display.
In the IIS log, I don't even see where it looks like it is being accessed when they attempt to load the app?
So, my question is, since this is FORMS authentication only, what could be causing it to NOT work based on which windows user is trying to run the app?
In other words, on the same Windows 7 machine, it works for 10 users, but not for others.
by the way, the application is remote - it is not running on the local machine.
The users ARE able to access the other ASP.NET applications hosted by the same IIS server in the same root inetpub folder.
The lightswitch application is using the ASP.NET v4.0 Classic app pool in calssic managed pipeline mode.
Any help greatly appreciated!!!
Happy to post any details/config/logs - I did not do so yet as I wasn't sure what would be most useful....
On the users machine you need to use Fiddler or the F12 tools in Internet Explorer to see exactly what calls are being made to the server and which ones are failing. LightSwitch is just an ASP.net website that launches a Silverlight application.
So the only other thing I can think of is that those users do not have Silverlight installed on their machines?
The users need to install the latest version of Silverlight. Apps built with LightSwitch 2011 require v4 or above and those built with LightSwitch for Visual Studio 2012 require v5

I'm developing a WPF XBAP application. When i try to open it in Internet Explorer (9.0.8112.16421 Update version 9.0.9 KB2722913, Windows 7) every time security warning is popped up. Twice.
That's very annoying and acceptable only in developer environment, there is a need to turn them both off. Project configuration is as follows : Security - "Enable ClickOnce security settings" (when its disabled application won't run at all) - "This is a full trust application"; "Signing" - "Sign the ClickOne manifests" (with test certificate which is imported to Trusted Root Certification Authorities). In IE both internet and intranet zones have "WPF browsers applications" set to "Enable" (that may not have effect because *.xbap is loaded from file system). In case I don't have alternative ways to integrate WPF application into browser (Silverlight is not an option, there is a requirement about full .NET framework targeting) i'm looking for solution of above described problem. Thanks in advance.
Problem was solved via manual addition of assembly's certificate (*.pfx) to Trusted Root Certification Authorities and Trusted Publishers as described here : http://blogs.microsoft.co.il/blogs/maxim/archive/2008/03/05/wpf-xbap-as-full-trust-application.aspx
I just lost 5 hours looking for a answer which i haven't been able to find :p
First, I'd like to force a trusted application (i need to access the file system) to display into the browser. Based on what i found on google a trusted application must be installed and launched as a desktop application (also called out-of-browser application).
So, i want to have an installed application on the client side but meanwhile, the user must also be able to start this same application into a browser window when he goes on my web site. Is this possible ?
Second, I'd like to give to the user the possibility to start the application from the browser. To be clear, the application is installed on the client computer but i want a button on my web site which starts the desktop application. How can i do that ?
Thanks
The answers are sort of and no.
Yes you can run an application that has been installed on the client also in the browser. However, not all of the installed application features will be available. Anything that requires elevated trust will not work inside the browser.
No you can't launch the installed application programmatically from within code running in the browser. The best you can do is display a polite message to the user to the effect that they have this app already installed and in order to access all of its feature they will need to launch it.
Yes, it is possbile since Silverlight 5, see my answer on silverlight-4-elevated-permission-inside-the-browser
I am trying to host a Silverlight 3 Out of Browser Application in Sharepoint 2007. My application gets displayed fine; but when I install it as out of browser; and try to run it from desktop; only blank screen is displayed and nothing happens onwards.
The XAP file is kept in _layout/MyFolder/MyApp.xap (Under 12 Hive). Am I missing anything?
My Silverlight app access Sharepoint data through its web services; I need to host it within Sharepoint so that it can access underlying Sharepoint web services.
It seems likely that the ClientHTTP stack used in the OOB mode is the problem. When hosted by the browser the app will use the BrowserHTTP stack and hence would share a common set of cookies. These aren't available in OOB mode.
How for example does the initial browser access to the Sharepoint site authenticate?
Creating an OOB experience against sharepoint may be possible but its likely to require more work.
Edit: Your problem is that NTLM authentication is not supported in the ClientHTTP used in OOB mode. Silverlight-4.0 supports this mode.
