Hi,

I have an XP machine to which I've installed Silverlight 1.1Alpha and VS Orcas Beta1.

This time I tried to install Silverlight 1.1 Refresh to the machine but rejected with
the error message as the subject.

I've also tried to install 1.0 RC and failed in the same result. 

I glanced at the system requirement page and I thought my machine was looked qualified.

I'd like to know what should I do to install the 1.1 Refresh?

Thanks in advance.

Hi Daniel,

I am getting the same message too.  Its an older machine with lower hardware, but 512 MB memory, and 1 GHz processor.  XP SP2 with IE7.  Ideas?

Can everyone who gets this error please post the full URL that that the link sends you to? If you get

http://www.microsoft.com/silverlight/help.aspx?errorID=1503

The purpose of the error is to check if your processor supports MMX and SSE instructions, if you get that URL also please post as much detail about your CPU as you can.

reedom, I'm trying to look up your processor now and see what happened.

reedom, it looks to me like you are using an early Athlon with a Thunderbird core. If that's the case, it looks like that processor doesn't support SSE instructions which are needed by the runtime.

Then you need to update the requirements to include the SSE requirements.  The requirements page that this error takes you to does *not* say anything about SSE instructions.  Also the error message should be changed to explain the same.

 Wow, that's bad.

Are you silverlight team going to eliminate machines having `a bit older' CPUs?
Or will this limitation be temporal?
 

In the formar case, I should rethink to accept silverlight as the platform of
our unborn software.

As far as I know the runtime uses the SSE instructions as part of its video playing, so I wouldn't expect the SSE restriction to be lifted anytime soon. I'll also note that the Thunderbird core was the last Athlon core to not have SSE instructions and it came out in June 2000, anyone using a chip from the Athlon XP series or newer should be fine.

There must be paperbacks in 100 years later world, I bet.
Readers still love still content.

BTW, how about to distribute a video-disabled version of Silverlight?

Yeah I've got an ATHALON (tm) 1GHZ from like '98 with 384K memory. It ran the alpha 1.1 with ORCAS beta 1 fine, but now it won't install the alpha 1.1 refresh or release candidate with ORCAS bebta 2 The expression blend 2 worked pretty good. 

 I've got an Applebred Duron, see below a dump from cpuz, what gives?
