Since I have no experience with this software, I can't tell you the exact route to the folder.
But I assume it's within the system disk
C:\System\Programfiles (x86)\ Name of the folder where software installed, maybe technics or something?

Some older software also install stright to the C disk without any optioons to choose where to place it, and folder is often named with the softwrename or sofware brand name.

A search for the software name at the PC may also lead you to the correct folder where the programfile (exe) is.
As soon as you find it, you can create a shortcut at your desktop by RIGHT click the file, and choose 'Send shortcut to desktop' or some similiar text in the 'bouble' that show up when rightclick.
