Unable to open file: VideoReDo Ver4.21


New member
After installing the program I try and open a file and I get that message. I am running windows 7 ultimate 64 bit. I have the same program on two other computers with windows 7 and I have no problem opening file on those machines. So there must be some kind of compatibility problem. Any ideas what needs to be done?
