Is the program abandoned?
I'm glad you liked it. I quit programming, so unless there's a very good reason the program won't be updated anymore.
Works on windows 64bit, I don't have an x86 installation to test it, sorry. Could you please post the whole problem signature?
Unfortunately, neither FreeImage nor wxWidgets can open those Maya IFF images, I would need to search for another library that can open them, but I'm not willing to do this, sorry. Probably you already know that, but you can open the animation in FCheck and convert it to another format. EDIT: In Maya's bin folder there is an app called imgcvt that can convert IFF to other formats, I did a quick test and successfully converted to a TIF that Veneta could read. I could use that exe inside my program...
