Unfortunately, the problem seems to be the order in which you installed and uninstalled things.
Yes, I'm sure you can go through codec fixers, 3rd party utilities etc... but I would STRONGLY suggest from experience that you do the following:
1. First, if possible, just restore the computer to a restore point - only if you have one from a date before you installed your programs. If you can't restore, continue to the next steps.
2. You should uninstall your AVID products, itunes, quicktime and any 3rd party codecs.
3. Use Revo uninstaller to make sure junk from these installations are completely removed.
4. Restart the computer.
5. Update Windows. SP2, .Net Framework.... etc...
6. Install the latest version of Quicktime.
7. Install the latest version of Itunes.
8. Restart computer (just for good luck )
9. Install your Avid products.
10. Restart computer (Just to be sure all drivers are loaded.)
11. Tell us if the problem is resolved. (Most important step )
It might seem like a pain to do all this but believe me that it will be faster than trying to fix a faulty system.
Thanks...but doen's work!
The problem surely is not in the Avid productes. Even after i have unisntall it and itunes, quick time, ect... with revo uninstall WMP couldn't run video files. I still get the stooped working message. I think i have some codec (s) broken. How can i corret that?
I have some new input about my problem:
I've notice that if i open the folder C:\Programfiles\windown media player and execute the WMP.exe file and choose to open some video it works fine!
The problem is that when i choose to open a file with windows media player it will automatically open with the WMP exe file from C:\Program files (86x)\Windows Media Player.
Something similar is hapenning with internet explorer. I get the same message as with the windows Media Player if i open using the icon from Program files (86x). But it works fine with the icon from the program files!
Why is this happenning if i have a 64 bit operating system??????
My problem is not solved because i need itunes and quick time to work, and my system don't accept the 32 bit instalation for this programs because it automatically detects that i'm running a 64 bit system, but when i install the lateste 64 bit version it is instaled in the ProgramFiles (86x) folder and i can't run the programs properly!
What a mess this 64 bit operating system!!!
It will tell you that you should download the 64 bit version but it will let you go ahead.
I have a hunch that if you get this installed and working you will be able to update to the 64 bit version and have it work too.
thanks for the sugestion mike, but i dont get why i cant use 64 bit programs in my 64 bit system. something is wronge here, and doing that wont resolve my problem. I want to be able to take advantage of the powerfull machine i supossly bougth...

But thanks a lot for your help. You are a fantastic helper...
