Installing the old (free) Nik Collection in PSE 2918

I need assistance with installing Nik Collection in PSE 2018.  Probably going to embarrass myself...had a computer at home for 35 years, but I am a user vs a techy. I can be dangerous poking around the bowels of the OS.   

Thanks for previous comments. Sepiana recently wrote: 
Copying/pasting the Google folder into the Plug-Ins folder will work for Windows users as well. However, this will not work in Clive's situation. Why? Because PSE 11 is a 32-bit program and PSE 2018 is 64-bit.
C:\Program Files (x86)\Adobe\Photoshop Elements 11\Plug-Ins\ . . .
C:\Program Files\Adobe\Photoshop Elements 2018\Plug-Ins\ . . .
This means that the Nik plug-ins (.8bf files) installed in PSE 11 are the 32-bit version. 32-bit plug-ins are not compatible with 64-bit programs. In this case, you need to run the installer (.exe file). The installer will do the job because it is designed to install both the 32-bit and the 64-bit version of the plug-ins. It will check the host program and will install the plug-ins accordingly.

" you need to run the installer (.exe file)." 

There are no [installer __.exe] files in the Adobe folder or Plug-In folder that I can find. Did a *.exe search in the Adobe main folder. 



There is likely a simple way to find and do what I need. 

Your assistance is appreciated. 

Thanks, 

Clive
