Silverlight installation problems

Posted at 2007-05-02 04:21 by Wictor Wilén in Internet Explorer , WinFX , Windows Vista , Silverlight with 4 comments.

I initially had some trouble installing Microsoft Silverlight on Windows Vista. It all installed perfectly without any warnings (not during setup nor in the Windows logs), but I could not get the Silverlight 1.0 beta applications to run. I guess that it had something to do with having installed WPF/E betas installed.

To get it to work this is what I did...

1: Start a command prompt using elvated privilegies

Click the Start button, enter "command", right click Command Prompt and select Run as administrator and the click Continue in the User Account Control dialog.

2: Navigate to "c:\Program Files\Microsoft Silverlight" and then write "regsvr32 npctrl.dll" and hit enter

 A confirmation dialog should appear if everything is ok.

3: Try a Silverlight application, like this one.

I wanted to see what Silverlight was like, i watched a brief video with it and when i went back to my Windows player is was off my computer. i cannot download it again. All versions will not download to windows 7 and the version 12 has no download available.

Screenshot from websnpr What worked for me to fix the problem, You should not install it with the IE browser opened... (constantly "download silverlight" even when it was installed) first I installed it directly from with IE, that did not work. then uninstalled silverlight, restart computer, downloaded silverlight (did not open/run it) closed IE then opened the downloads folder and doubleklicked silverlight.exe after installation again restarted thee computer, after this started IE, now silverlight worked like a charm.
