Not sure if anyone will be able to assist, but I'll try my luck.
So random applications and stuff can be merged with Skype to forward the desired messages there if needed and so can Haven. Application works through API, where info is sent to Skype, where in first time you should get a pop-up, asking you to allow or not allow the application to use the Skype. When you allow it, application will then use Skype and be able to forward messages through it.
I managed to get one working on a laptop with XP 32 bit system, newest Skype version, but am unable to get it working on current laptop with 64bit Win7 system (not that I know if OS plays any role here). Problem I have is, that I don't even receive the pop-up in Skype asking me to allow application to run. I can however go manually to options - advanced settings - manage applications and I can see the application there, can set it on "allow", tho this does not change anything except that visually its now set to allow. It still does not work and I'm getting same error as before: Skype message failed, com.skype.NotAttachedException.
Anyone knows what the problem might be? I've tried 5.0, 6.1, 6.5, 6.18, 6.20, 3.8 and even Skype portable version of Skype and they all have same problem.
