I tried to manually register npctrl.dll and I get DLLRegisterServer Failde Error Code 0x80070005.

Ditto...same error here when trying to manually register.

I have determined that the reason Silverlight is not recognized by IE7 in my installation is that the following line in Silverlight.js (part of a version check) fails to create the object:

var AgControl = new ActiveXObject("AgControl.AgControl");

Curiosly, I can create the silverlight control using the object tag. Following Joe Stegman's demo I created the following html page in my local machine

and dropped the following test.xaml file in the same folder

<Canvas xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
<TextBlock FontSize="32">Hello World!</TextBlock>
</Canvas>

and everything worked fine! (I get a prompt about running scripts or activeX but after I allow blocked content I see Hello World!)

Obviously this is a registration issue. The install left two files in c:\program files\microsoft silverlight\, agcore.dll and npctrl.dll. I am tempted to register them manually but I'll wait to see if anyone can shed light on why the object tag works and new ActiveXObject does not.

Found it, works now on my system :D

In addition to this steps from http://silverlight.net/forums/t/600.aspx:

-I have deinstall ALL orcas and silverlight programs with the system control panel
-I have delete the complete registry key Typelib\{283C8576-0726-4DBC-9609-3F855162009A} not only the 8.5/8.0 subentry
-I have delete this npctrl.dll
-I have cleared my cookies, temp Internetfiles and my TEMP folder

-I install Orcas from http://www.microsoft.com/downloads/details.aspx?FamilyID=5d9c6b2d-439c-4ec2-8e24-b7d9ff6a2ab2&DisplayLang=en
-I install Orcas Tools from http://go.microsoft.com/fwlink/?LinkID=89149&clcid=0x409
-I install Silverlight alpha 1.1 from http://go.microsoft.com/fwlink/?LinkID=89145&clcid=0x409

I am not sure if the reinstall of orcas was the trick, and if this is needed or not, but it works now.

This is not working for me!

Silverlight still does not work on IE (works fine in Firefox though) is there any incompatibilities with existing plugins?

The only solution that I have found yet is:

rightclick in the quickstart on the IE symbol and choose "Run as admin"... (MS are you serious? IE run as Admin? )

Yes, I have delete the registry key HKCR, Typelib\{283C8576-0726-4DBC-9609-3F855162009A} and deinstall previous versions, no luck.

I have the exact same problem and I tried to uninstall install reboot etc nothing works...

Is there a way to force a clean uninstall?
Some registry keys to add or remove?

If already 5 people have the same problem (and actively searching for a solution) after 2 days, it's going to be thousands in a few weeks....

The same problem has been reported in other threads in this forum. I can confirm that the problem is specific to IE7. If I run Firefox 2 everything works fine, meaning that the 1.0 samples work as expected. So 1.0 beta is installed, it's just not recognized by IE7, which keeps prompting for an install.

The registry shows version 0.90.20416.10 in HKLM\Software\Microsoft\Silverlight. Following the advice on another post I removed entries for Typelib\{283C8576-0726-4DBC-9609-3F855162009A} from HKCR and HKLM\Sofware\Classes and reinstalled, but it hasn't helped IE7 in my case.

So the short answer for now is to use Firefox. Sweet irony.

Thanks Steve. I am aware of the difference between 1.0 and 1.1. I will probably install the 1.1 alpha bits on a virtual machine, but at the moment I just want t get the 1.0 beta working.

I have been to the page you suggest a few times. It tells me to "install now". I go through the installation and tell UAC it's OK, the installer extracts the files and I finally get a screen that says Silverlight 1.0 has been installed (with a beta label on a corner). But if I go back to that page, even after a reboot, it still tells me to "install now". And the 1.0 samples do the same. (The same page on my work machine shows Silverlight as installed.)

My theory is that the problem is caused by some remnant from the February CTP version of WPF/E.

Many of the samples are utilizing Silverlight 1.1 Alpha. You have indicated that you installed the Silverlight 1.0 Beta. A way to validate that Silverlight is installed properly is to go to the following site http://www.microsoft.com/silverlight/install.aspx. If the background is blue (and you are not asked to install) Silverlight is installed successfully.

If you want to install the Silverlight 1.1 Alpha go to http://www.microsoft.com/silverlight/downloads.aspx and install the "For Developers only: Download Silverlight 1.1 Alpha" at the bottom of the page.

Thanks,

I have tried installing 1.0 beta a few times with and without reboots but without success. "Microsoft Silverlight" is listed in programs and features, and the registry shows version 0.90.20416.10, but none of the samples run, all I get is the link to install. I had wpf/e installed and I probably failed to remove it first, but there are no traces of it that I can see. Any way to recover?
