It seems that you're using an outdated browser. Some things may not work as they should (or don't work at all).
We suggest you upgrade newer and better browser like: Chrome, Firefox, Internet Explorer or Opera

I resolved this Bug by:

1. Deinstallation
2. Deinstall ALL fdshow Applications (the one which is shipped is the "Problem" in my case)

-> I had fdshow filters (other, newer version) installed in 64bit...

3. Install the game again
4. Just click "next" in the fdshow-setup (which installs a 32Bit binary if I am not wrong)

Game started to work

It would be kind if the Setup would check if fdshow is already installed so a Installation of the old fdshow is not required.

Kind regards,
