Warning: An error occured while opening one or more files.

So recently I tried using Vegas Pro 17 with AVI files but it didn't seem to work. I learned that I needed a codec pack for them to work, which I installed. Now, it works 50% of the times and when it doesn't, I get an error message saying "Warning: An error occured while opening one or more files. The file is most likely corrupted or of an unknown format." The problem is not with my computer since my computer reads it as an AVI file, but Vegas doesn't for some reason. Does anyone know how to fix this? It's getting really annoying, I have to re-shoot my video all over again for it to work.

You may have done less good than harm by installing an invasive codec pack on an editing machine. Suggest you roll it back to a saved system backup and start proper troubleshooting.


Now, please read this post thoroughly, including #12.

There are hundreds of different codecs possible in the AVI container, and that's where we need to start. Thanks!
