i have downloaded the divx 4.12 codec, but whenever i try to install it, it tells me there is a "error opening file for writing: C:\windows\system32\divxdec.ax"
what do i do?
Delete the setup file and re-download it from DivX.
Then try to install it again. If it still doesn't work, email DivX and tell them what file is giving you the problem. DivX has really good Customer Support, they should help you.
