Packaged for deploying silently via SCCM, using hints found from people packaging earlier versions.
This is for the 'Named License' version not the Enterprise version, so no license code is added during deployment.

Installation files were extracted from the main source: PhotoshopElements_14_LS28_win32.exe
This creates 4 folders (deploy, packages,payloads, resources) and 2 executable files (oem.exe, Set-up.exe)

Silent Install - (these switches aren't documented anywhere)
"oem.exe" –P PSE

Silent Uninstall - create an AutoIt script containing the code shown below:
RunAsWait('admin_account_name',@ComputerName,'admin_account_password',0,'Set-up.exe --mode=silent --deploymentFile=' & @ScriptDir & "\deploy\remove\remove.xml")

The remove.xml file already exists as part of the source files.

For the uninstall I ended up using the AutoIt script to overcome problems with path re-direction and administrative permissions. This is probably achievable with a simple command line directly into the SCCM uninstall line - but I don't have the silky skills to do that yet.

Adobe error 16 appeared each time and the solution to overcome this was more effort than the AutoIt script - KISS

We did try - honest.
