How to make Vegas Pro open AVI files

Question

In using Vegas Pro 13 on a new Windows 10 computer, I find that I cannot open AVI files. It's not a codec issue; the file will not open at all because Vegas doesn't recognize it as a type of file it can open. I've used Vegas Pro for years and do not remember having this issue, but it has been five years since I got a new computer. I've had trouble with the codecs in AVI files, but they always opened.

How can I fix this issue?

Answer 1

It seems that sometimes Vegas Pro's plugin that opens AVI files is corrupt or installed incorrectly (if this is the case, a reinstall may fix it).

There is a simple fix that involves replacing the DLL file that controls AVI files.

The file is called aviplug.dll. The file path will be similar to: C:\Program Files\Sony\Vegas Pro 13.0\FileIO Plug-Ins\aviplug\

• The fixed dll can be found at Mediafire.
