Hi Youki,
When you create EXE, you can not run it directly on any PC without installing RTE. Instead of just creating an EXE, you can create installer.
Check the below link on how to create Installer
http://zone.ni.com/reference/en-XX/help/371361F-01/lvhowto/build_installer/
When you create installer, you will be including required drivers and RTE.
you will know the difference by seeing its size
Then you just run this installer on a PC where you want to use.
