17528: ARM Processors – Issues Viewing / Serial Number Issues

Networks + Operating Systems

Why does my serial number on the ERO screen not match what I entered? Also, I am having trouble viewing or calculating tax returns in the software.


When you experience issues with your serial number entry, or viewing/calculating tax returns, the first thing to check is the type of processor that your machine is running. It is likely that your machine is running a processor using the ARM-based architecture. ARM-based processors are not currently supported by any Drake Software product.

To check which type of processor your computer uses: :

  1. Open Settings.
  2. Click on the System icon.
  3. Click About on the left side menu at the very bottom. 
  4. Under Device specifications on the right side, check the System type. This will indicate either a x86-based processor (32-bit), x64-based processor (64-bit), or an ARM-based processor.


What are common computers that use this processor type?

Many laptops are currently using ARM-based processors. Examples include: Microsoft Surface Pro, Samsung Galaxy Book, HP Elite Folio, Lenovo Flex 5G and the Acer Spin 7.  Additionally, the entire Apple “Mac” line of desktops and laptops currently in production (as of late 2020) use the M1 chip, an ARM-based processor.

If your computer is not running with an ARM-based processor and you continue to experience issues, please contact Drake Support for assistance at (828) 524-8020, 

Can I use Hosting on Right Networks to access Drake if my computer uses an ARM processor? 

Generally, yes. As long as the other system requirements for Right Networks are met, you should be able to use that computer when accessing Drake through Hosting on Right Networks.
