It works!
Now, I did it a little different because it seems Vista is different and my laptop is in dutch.
I couldn’t find the codec list, so I googled the Fraunhoffer thing for vista.
It appears Windows and Fraunhoffer have a bit of a fight, now every Vista still has Fraunhoffer’s thing but it is still on, in TWO files.
The problem is that the advanced is working and the professional (the needed one) is deactivated.
By using a patch, the advanced is deleted and the professional is activated.
By using this, and deleting all old saves and restart.fl, it now works like a breeze.
I’m so happy!
I don’t know if I’m allowed to link to a other site, but I’m going to take the risk because here is where the patch is:
