Silverlight failed to install (1.0b or 1.1a)

05-02-2007 2:22 PM |

 Hello,

 I'm trying to install Silverlight 1.1 alpha but the installation keeps failing each time giving me this link http://www.microsoft.com/silverlight/help.aspx?errorID=2

The problem is that i already uninstalled the previous CTP Feb 2007 WPF/E installation and no other CTP or Silverlight plug-in are actually present in the Add/Remove entry.

In the mean time i have installed Orcas Beta 1 and the Silverlight extension for Orcas as well as the Expression Blend Preview 2 but i can't compile a project without the runtime for Silverlight 1.1 alpha obviously

Is there a way to determine why the installer keeps bugging me about previous install if none are present as far as i can see? Any way to bypass this validation?

 <Edit>

I forgot to mention that i'm using WinXP SP2 that include a full VS 2005 SP1 (with a lot of extensions such as WPF, WF and WPF/E templates and vista SDK) and as mentionned before Orcas Beta 1 with silverlight extension

Thank you in advance

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}\0.8
HKCR, 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}\0.8
HKLM, SOFTWARE\Classes\Typelib\{283C8576-0726-4DBC-9609-3F855162009A}\0.8.5.0

Thanks

 Hello,

 Thank you for your answer e_screw.

Unfortunatly i have no such registry entry on my computer. I also tried to locate about all other entry possibly connected to a CTP release (like anything using the "CTP" tag, "Feb 2007" and so on) but i can't find anything.

If anyone could possibly know what the Silverlight 1.1 alpha installer checks on the machine in order to tag my computer as an invalid environment that would be very helpful.

 Thank you in advance

Hello,

I have same issue, but I hadn't installed previous CTP Feb 2007 WPF/E.

I'm using WinXP SP2 vs VSTS 2005 SP1.

Can anybody help me?

Kind regards

I have the same problem it extracted the content to my "J:" drive instead of C: but it erases everything before I got time to copy everything... how do you stall the install?

For me the install runs fine but it does not register the activeX for IE

Hi,

 
Exactly the same problem here on XP SP2. Your fix solved the issue. Is anyone at MSFT listening? Something is not right there.

 
Greetings,
