@ the OP:
If you are on a Mac:
Can I use both 64-bit and 32-bit versions of Reason 6/Essentials/Limited on my 64-bit Mac OS X system?
Yes, you can!
On Mac OS X, the Reason application itself includes both 32-bit and 64-bit resources. This means the program will run in 32-bit or 64-bit depending on your operating system - you don't actually need to do anything when installing the software.
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). In this case, you can force the program to run in 32-bit mode in the following way:
Select the Reason application.
Select "Get Info" from the File menu in Mac OS X.
In the Info dialog, tick the "Open in 32-bit mode" checkbox.
When you now launch Reason it will run in 32 bit mode.
If you are on Windows:
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:
Create a shortcut of the "Install Reason.exe" file.
Right-click the shortcut and select "Properties".
In the "Target" field, add " /32" (without quotes, keep the leading space) at the very end.
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.
