CoCreateInstance fails if Reader-X protected mode is enabled

Question

Hi,

  

My application creates a plug-in for Adobe Reader X.

 

The application dlls are strong named.

 

The plug-in loads a COM object.

The plug-in works fine when protected mode is OFF.

 

When the Reader X Protected Mode is Enabled , the 'CoCreateInstance' fails with "Class not registered" error.

If i remove the Stong name for all the dlls i wont get the above error , the Class successfully registers.But i cant do the same for 3rd party dll and removing Strong name is not the good way for fixing this issue.

  

Please someone help me for fixing the above issue without removing the Strong Name for all the dlls.

Thanks in advance.
