There are several scenarios where Internet Explorer does not show a certificate for a signed .cab file. The following section describes those scenarios.
Here are the three most common reasons for this behavior:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinTrust
These privileges can be granted by a user on the machine who has administrator privileges using Regedt32.exe. This requirement will be addressed in future versions of Internet Explorer.
Note If the certificate does not appear or you answer No to the certificate, the applet will still load but will not be trusted.
