Vista Home Premium, 32 bits.

I downloaded and installed the free Flashback Express screen capture software 2 days ago. I like the program's ease of use and functionality but it only offers 5 codecs to save the screen capture to AVI: DivX 5.1.1, 2 intel codecs, Microsoft Video1, Cinepak by Radius and Full Frames (uncompressed). Since DivX is the only codec of the 6 I'm familiar with, I tried first to export my project using it. It failed. I've tried it again and it still failed. The program is supposed to come with these codecs so I'm assuming the export failures aren't because the codec isn't installed on my computer and no explanation is given in the "failure" pop up.

Does anyone have any idea about what might be going on and what I might do about it? I've already found the program's folder that contains the codecs and was wondering if I could just install a K-Lite pack in it.


Thank you.
