I assume you're on 64-bit Windows.
If so, the easiest way is to browse your C drive.
If the program is installed in the C:/Program Files directory, it is a 64-bit program.
If the program is installed in the C:/Program Files (x86) directory, it is a 32-bit program.
Thanks! Such a simple solution but it didn't occur to me.
What program are you using - Photoshop Elements 13 or Premiere Elements 13 - what computer operating system?
If you are installing Premiere Elements 13 specifically on Windows 7, 8, 8.1, or 10 64 bit computer, then Premiere Elements 13 is a 64 bit application.
If you need further proof...
a. determine if it has been installed under Program Files or Program Files (x86).
b. use a software such as Process Explorer Sysinternals and its Image Type column
c. Open the Start Task Manager in the Taskbar of you computer...if the opened Adobe Premiere Elements.exe process has a *32 next to it, that is a 32 bit application in your computer.
