Windows 7 Can not activate "Windows Communication Foundation non-HTTP"

[Trollwut]

Hi guys!

I try to play GTA IV on Windows 7, but the RGSCLauncher.exe wont start.
Googled for some days and maybe I found my problem.

I have to activate "Windows Communication Foundation non-HTTP Activation" on the menu for activating Win-Features, but it always fails.

I get an error saying just "some parts could not be activated", but I can only click on "OK" and it gives me no more description.

Anybody got an solution for my problem? I would be really thankful.

Hi bcaroll!

Yes, it requires another thingy in this dialogue to be activated, as i read. But this is already activated.

It does not require Win-CD, as i saw, but the CD is in the drive.

Woohoo!
Maybe I found a solution.

It was raised in a Win7-Forum and is also a solution for Vista.

There it is:

Link Removed - Invalid URL

But my problem is, that I cant find any of these packages.

=> Link Removed due to 404 Error

As you may think... I need help... :/
