Hello,
I've just installed both Silverlight 1.0 beta and 1.1 alpha each at a time on my machine. The problem is that any page that has silverlight content shows me the "Get Microsoft Silverlight" logo although it's already installed.
I tried the same websites on Firefox 2 and they work like a charm.
I think something is wrong with IE but I can't get it to work right.
I'm using Windows Vista Ultimate and the problem is with IE7.

I see this problem as well, and it looks like a bunch of other people do too!
Anyone know how to get this working with Vista?

Uninstall all the previous CTP release and then try a clean installation. I am not sure though, either the Beta 1.0 or Alpha 1.1 is working on IE 7
Thanks

I don't remember installing a CTP and I have nothing listed in Add/Remove programs. Neither 1.0 or 1.1 works.

I did uninstall the February CTP before trying to install either but still none of them works !!!
The funny things is that Silverlight - a Microsoft product - is playing better with Firefox !!

Can you try running IE7 as administrator and checking to see if Silverlight works okay? Don't leave it running as administrator after you check since that isn't a recommended configuration from a security perspective.

Running IE7 as administer fixes the problem. More details here.

If running IE7 as administrator makes Silverlight content render properly and you may have had a WPF/E CTP installed previously the problem is likely a stale Typelib regkey in HKEY_CLASSES_ROOT. The CTP has been known to leave behind stale Typelibs for version 0.8 and 0.8.5.0. The correct Typelib version for both the 1.0Beta and 1.1Alpha is 0.90.
If you are comfortable editing your registry then you may choose to manually delete the old Typelib regkeys:
HKCR, Typelib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8HKCR, Typelib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8.5.0
If Silverlight in IE7 doesn't work as administrator but you may have had a CTP installed previously you might also see if you have either of these keys under HKLM. If so, you can delete these two as well.HKLM, SOFTWARE\Classes\Typelib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8HKLM, SOFTWARE\Classes\Typelib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8.5.0

Running as an admin didn't work for me, but I found the stale registry key. I found and removed
HKCR, Typelib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8
and then it worked just fine.

To make editing your registry a little easier/safer - copy and paste these into a command prompt running as administrator or into a batch file that you then run in a command prompt running as administrator. The /f eliminates the are you sure prompt - if you omit it, be sure to paste the lines in one at a time so that you can answer the prompt.
reg delete HKLM\SOFTWARE\Classes\TypeLib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8 /f
reg delete HKLM\SOFTWARE\Classes\TypeLib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8.5.0 /f
reg delete HKCR\TypeLib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8 /f
To get a command prompt running as administrator, click the start aka vista logo button, then click All Programs, then expand Accessories, then right-click on Command Prompt and select Run as administrator.

Hello, i'm trying to install the silverlight SDK february edition, but always get the same "install silverlight" error. Although i have install the SDK over and over again.
I'm currently using windows vista, ie 7 and firefox 2.0.0.3. Also had Visual Studio 2005 sp1 in it. The error message always shows up when i run the WPFEJSApplication template project (from installing the WPFE VS Template from the WPFE SDK february edition).
I've been searching this forum, do the suggestion from all of you people in this step :
and the result is, the install silverlight logo is gone, but the page is done but with errors on page on IE7. While in the firefox, the button "Click me" shows up but i can't click it.
oh yeah, the error on IE7 is 'undefined' is not an object on line:182 char:9
Anyone had any suggestion for this?
Thanks before

I had the reg keys correct up higher but cut & pasted wrong when I replied with the reg delete command lines - I fixed them by editing my previous post.

Need helpppp i'm still stuck on the same problem here...
Every application i make/run from Visual studio 2005 always say "done but with errors on page"But my browsers can open this page without error http://www.telerik.com/demos/aspnet/silverlight/Cube/Examples/RoomDesigner/DefaultCS.aspx
Why the error only shows up from developing a Silverlight project?
Thanks for any suggestion :)
