Registry permissions

Hello,

I'm using Installshield 2011, and would like some help setting a registry key permission.

I have the Locked-Down Permissions set to Custom Installshield handling, and the reg key: HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\Root\ProtectedRoots, set to [%USERDOMAIN] \ Everyone, Full Control (just to try and resolve the issue).

But when I save the project, and then try to run it, I get the error, "Could not open key: HKEY_CURRENT_USER\Software\Microsoft\SystemCertificates\Root\ProtectedRoots..."

Does anyone know why I would get this even with the permissions set to Everyone \ Full Control?

I also tried [%USERDOMAIN] \ Authenticated Users, Full control. But got the same error.

Thanks for the help,

Vince
