Answer 1

Go to your Certificates and find the tab Trusted Publishers, your certificate should be there

Every client should have the certificate there.

Once you checked this and can confirm that everyone has this certificate, you should run this registry (64bit):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Silverlight]
"AllowElevatedTrustAppsInBrowser"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Silverlight\Components]

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Silverlight\Components\Debugging]

(32bit)

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Silverlight]
"AllowElevatedTrustAppsInBrowser"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Silverlight\Components]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Silverlight\Components\Debugging]

Just save this into a .txt file and rename it to .reg and run it. This should fix your problem.
