I just installed WINcdEmu on my Windows 7/64 pro system and it simply works. This is better (for me) than the three other leading freeware CD/DVD emulator softwares that I have recently tried.
I had one hitch with ISO files. My Windows had decided that all ISO files are sent to ImgBurn with no exceptions. Double clicking on any ISO file opened ImgBurn. I found a simple way to un-associate ISO files from any software and now everything works great. I have different softwares open ISO files as I wish.
