How do I install the 64 bit version of MultiBit? I downloaded the MultiBit client that is supposed to be compatible with 32 bit & 64 bit but when I run the program it give an error message that says that the program is incompatible with the current version of Windows that it is being run under. How do I get the MultiBit client to run in 64 bit?
This can be caused by the multibit.exe executable not being able to find the 64 bit version of Java. There is some discussion about it on the MultiBit issues database here: https://github.com/jim618/multibit/issues/376
tl;dr If you install the 32 bit bit Oracle Java runtime MultiBit should find and use that.
