I've found these very small and very large cards to have issues.
Try the workarounds such as an external USB media card reader and be sure the OS supports 64GB cards.
I'm guessing that it is not 64MB since the micro SD cards didn't show up at that size here.

I bought a An Adapter with SDMicro. When I plug it into the computer(desktop), the computer does not recognize it. I also have a 64MB SD Micro. When I plug that one in the computer recognizes it. I took it to Visions and they tried it on a laptop and the format dropdown menu came up. I am using Windows 7 now and it still does the same thing. Where is the formatting software located as I can't find it?
Any suggestions would be appreciated.
