I have a problem with ACE Mega Codecs pack.I start installing it and almost at the finish it says DashBoard is configuring your system and then it stops and give me this error: External exception C000001D and also blocks the system!
Any ideas??????

I had this pack a while ago. After installing a lot of things were not working well.

At least I deinstalled it ( deinstalling caused some problems,too ), checked the files with "G-Spot" and installed only the codecs I really need. That was the better choice.

I recommend to read the pinned topic "Guide to using codecs".
