How I manually installed drivers on Windows 10 for my edirol um-2ex interface. Don't know how to post it so I thought I would leave a message with you
Basically you need to download the UM2_W81D_V....ZIP (32 or 64 bit as appropriate), then extract the files IN THE APPROPREATE SECTION 32 OR 64 BITS. MAKE A NEW FOLDER WITH NAME
EX. (EDIROL) AND EXTRACT THE FILE INTO IT. USE THIS FOLDER TO MAKE YOUR MODIFICATION.

Then search the extracted folders for RDIF1003.INF or something similar. Modify the .inf file BY DOUBLE CLICKING ON IT SO you can open it and see the literature. All occurrences of "NTamd64.6.2" become "NTamd64.10.0". MAKE THESE CHANGES AND DON'T FORGET TO SAVE THEM. I BELEIVE THERE ARE TWO OF THEM Then manually install the driver by going to device manager, right clicking on SOUND AND VIDEO etc. to black it out. then go to the top of device manager and open ACTION. FOLLOW THE PROCEEDURES TO INSTALL THE DRIVER MANUALLY. WHEN THE FILE RDIF1003.INF IS INSTALLED THEN YOU CAN PLUGIN THE MODULE INTO THE USB PORT AND THE DRIVER UM2 SHOULD SHOW UP IN THE DEVICE MANAGER (SOUND VIDEO ETC) WHEN YOU DOUBLE CLICK ON IT.
THIS IS THE OPTION THAT WORKED FOR ME.
