I am using Silverlight but whenever I try one of the templates for output, an error message would appear saying that Silverlight does not exist.

So I tried reinstalling it, but the installation has detected that the same version has already been installed on the computer.

With this, I uninstalled Silverlight along with its tools and data files but the error is still there.

I also use Expression Encoder 3 on my Vista. It has worked without any problem before it was restored.

I have been on this problem for a week now, and I am still unable to find a solution to this problem. I desperately need your suggestions to resolve this problem.

Unable to install Silverlight

The same version of Silverlight is

The template has some codes which work well at Vista and Silverlight.

All you need t write the template code where the error is thrown.

Try to debug the code and find the code where it is creating problems.

Type the code and send back. There must be some solution to the problem.

Once you are acquainted with this type of problem you shall be able to download any templates and then configure for your own purpose.

You may also install the VMware for the Windows XP then install Vista to it.

Try deploying it in a server and check.

To fix this error, do the following:
1. You need to know first if your system using 32 bit or 64 bit Windows Vista.
If it is 64 bit check this directory:
C:\Program Files (x86)\Microsoft Silverlight
Otherwise if it is 32 bit check the following:
C:\Program Files\Microsoft Silverlight
2. You should see one directory and two files in the folder which are:
A. 4.0.50917.0 (or depending on the version installed on the computer)
B. sllauncher.exe
C. xapauthenticodesip.dll
3. Run another browser aside from Internet Explorer such as Google Chrome. This is to check whether the problem is in the Silverlight installation or in Internet Explorer. If Silverlight works in Google Chrome then the problem is in Internet Explorer.
4. Restore your Internet Explorer to its default settings as discussed in this Microsoft support page.
5. Open Internet Explorer then click Tools > Manage Add-ons. Check if Microsoft Silverlight is enabled.
Close everything and check if the problem is resolved.
