You can, but it is only for AVI headers -- doesn't add frames, so you would lose audio sync I think (it's been a long time).
BTW, there are a bunch of "oldies but goodies" on that site -- the little snowflake creator for web pages and AVIEdit (great fx + takes Photoshop .8bf filters) have been on my system for well over a decade.

As musicvid10 states, all AVIFrate does is to patch the AVI file header. However, this is often all you want to do. Put another way, it does not add or delete any frames; it merely speeds up or slows down how fast the existing frames get played.
Think of AVIFrate as being the same as the speed control on an old film projector: the film still has the same number of frames, but by turning the knob you can get them to play faster or slower.
The audio issue, of course, is quite real because the video is going to take more time, or less time to play so the audio will have to be re-synced. Fortunately this is trivial to do in Vegas (just "ctrl-drag" the audio event edge to match the new video event length). When you do this, you usually want to keep the pitch the same.
Also, if your Vegas preferences are not set to default to "Elastique" pitch control software, make sure to right-click on the audio event(s) and make that change.
I use AVIFrate almost every day and couldn't live without it. I just wish there was something similar for other container formats.

This is also the most common way to conform Film->PAL DVD as well.
Flags the DVD (not the Mpeg header) as 25 fps rather than 24 or 23.976, which is probably why most Europeans talk a little faster and higher-pitched . . .J!
