interop dlls not downloading with embedded dll

[BryanZM]

I have a embedded control in IE that uses some com interop dllls. On some computers when i open my web site the embedded control does not work. i have tracked this down to the interop dlls not getting downloaded into the downloaded assembly cache on those PC's. I have checked security and those PC's are wide open to my site. What may be the reason they are not getting downloaded with the rest of the assembly?

 

Thanks and much appreciation for all help.
