Error : Cannot load a dll in extension

Error : Cannot load a dll in extension

  
My problem is very similar to this one:

http://www.outsystems.com/networkforums/viewtopic.aspx?forumid=26&topicid=3352

However i'm still unable to solve it. I have an extension which has some SNMP dll and when i try to run the program in service studio it always gives an error saying it was unable to load that dll.

If i do a pure test in .net it works so it should be a problem concerning importing the DLL.

Any clue ?

SOLVED: Had to register DLL on the server gac.
