Opera DIM issue

Grendors

Hello Guys and Gals,

I am having a problem with Opera browser and DIM.
I started using Opera Browser recently and when on daz site if I get content and click the Download and install using dim button i get and error message.
The message is "

Unknown protocol

Opera was unable to open the link since no application
associated with "daz3dim:" protocol was found on your system."

Yet if I open firefox and click button it works fine.

 

How do I get button to work properly with Opera Browser? Please.

 

Thanks in advance

Grendor
