Yes, I understood that and you said it was 32 bit on the other device. Since you should install it in 64bit. If that doesn't work then converting the file will probably not work either. What is the difference between a file made with the 32 bit and thus a 64 bit file?

You can open the file, edit it and do the same with this file on a 64bit computer.

Excel understands its files on both 32 and 64 bit computers.
