Do I need to download the 32 or 64 bit version of EDT Single-user?

If your operating system is running in 64-bit, it is better to download the 64-bit version of the application, which allows faster data processing than the 32-bit version. To find out if your operating system is running in 64-bit, open your file explorer with the keys Windows + E; in the explorer window, right-click on This PC, then click on Properties in the drop-down list.
