Yes, DIMA will run fine on the 64-bit version of Windows operating system. However, you will need to run the 32-bit version of Access (Microsoft Office). It is unfortunate that Microsoft released two versions of Access, a 32-bit and a 64-bit version, that use different programming. We had to make the decision not to support the 64-bit version of Access since it meant we would have to re-program DIMA from the ground up and then support both versions.
