how do you label a topic as 'fixed'?
Dont know, never started a topic myself, yet.
Apparently you can't mark your own post as 'the solution'. That's pretty lame! What if you found out how to fix your own problem and wanted to share it? -_- GOG needs to fix this.
Thats rude! The solution was a reinstalling of Windows, wasnt it? Also I was the first in this topic that said this (even if I was kidding at this moment):
Reinstalling Windows? :P
Strangely enough, i now have 6 important updates that cannot be installed in windows. One cannot say 'it's due to a bad installation of windows'. I think they are merely bad updates that microsoft just shat out for no reason and that don't work.
I have installed Windows 7 64 bit just a short time ago on some completely different computers, with different hardware and with different settings and configuration, even with some low level changes on the system itself and couldnt experience such problems on any of them nor on any of the computer that is running this system for a while now.
Even that I know that it could be a problem on microsofts side, especially because they already had broken updates, I still really think, that you broke your system yourself, again (with any suspicious software, like the mentioned codec packs).
Even after you uninstall the codex packs (For me it was the old ace mega codex pack which is way outdated, then a newer codex pack that was lighter on the codex but gave me essential codex I needed for virtualdub), the conflict will not (REPEAT, WILL NOT) go away.
It will go away, if you know how to do it! Of course it maybe wont go away by just pressing uninstall...
A maybe easy way to repair such things could be the DSF/MFT Viewer of the DXVA Checker Tool, that helped me many times already (because of the broken Video Hardware Acceleration of Ati Graphics Cards). But there exist also different alternatives, one would be to do it yourself :P (but most people just cant).
