NI recommends creating a separate installer for the 32-bit version of a test system and for the 64-bit version of a test system. If you use the deployment utility to build an installer that includes the TestStand Runtime, the utility also includes dependent runtimes if any are necessary.

Installers you build with the deployment utility install files to different directories depending on the bitness of the deployment utility you used to build the installer, as shown in the following table.

Destination 32-bit Directory 64-bit Directory
TestStand directory 32-bit TestStand directory 64-bit TestStand directory
Program Files 32-bit operating system: Program Files64-bit operating system: Program Files x86 64-bit operating system: Program Files
National Instruments directory 32-bit National Instruments directory 64-bit National Instruments directory
TestStand Public directory 32-bit TestStand Public directory 64-bit TestStand Public directory
TestStand Application Data directory 32-bit TestStand Application Data directory 64-bit TestStand Application Data directory
System WOW64 directory N/A <Windows>\SysWOW64
Note 64-bit operating systems store 64-bit libraries in the System32 directory and 32-bit libraries in the SysWOW64 directory. When you create a 64-bit deployment, install shared libraries in the System32 directory and install 32-bit libraries in the SysWOW64 directory. Refer to Microsoft MSDN documentation for more information about using a file system redirector.
