Can I use both 64-bit and 32-bit versions of Reason 6/Essentials/Limited on my 64-bit Windows system?

Yes, you can!

In Windows, there is a single Reason installer containing both the 32-bit and the 64-bit version. When you run the installer, it detects if you’re running a 64-bit OS, and automatically installs the 64-bit version of Reason. Otherwise, the 32-bit version is installed.

It might be desirable to run the 32-bit version even under a 64-bit OS (for example if you’re using Reason with ReWire and a host that only supports 32-bit ReWire). Then, you can force the installer to install the 32-bit version in the following way:

  1. Create a shortcut of the “Install Reason.exe” file.
  2. Right-click the shortcut and select “Properties”.
  3. In the “Target” field, add ” /32″ (without quotes, keep the leading space) at the very end.
  4. Click OK.
  5. Double click the shortcut to run the Reason installer in 32-bit mode.

Forcing a 32-bit installation this way should give the name “Reason (32)” to the desktop icon and Start menu folder.
