Installation Error - Acrobat DC Pro - New Purchase - Fix or Standalone Installer request

Hi

I have just purchased Adobe Acrobat Standard DC Commercial Edition  and the install fails via Creative cloud as per the error below;

Exit Code: 7

Please see specific errors below for troubleshooting. For example, ERROR: DW003, DW071 ...

-------------------------------------- Summary --------------------------------------

- 0 fatal error(s), 2 error(s)

----------- Payload: Adobe Acrobat DC 17.9.20044.0 Adobe Acrobat\Setup.exe_17.009.20044 -----------

ERROR: DW071:

ERROR: DW003: Third party payload installer Adobe Acrobat\Setup.exe failed with exit code: 1603

So far I have removed all adobe products , also removed other installs not listed on uninstaller via Microsoft removal tool , used the Adobe Acro cleaner tool ,cleared the temp folder cleared any remaining adobe files and then tried again  running as administrator, as a last resort I grabbed two offline installers but these don't seem to recognize my serial number or just dont work being a CC product to proceed any further. Can someone confirm an easy fix that I am missing or advise of a location of an offline installer that will work.

Version purchased Adobe Acrobat Standard DC Commercial Edition PC Download | Officeworks ​

Download Link is the Creative Cloud Install but this fails about 70% through each time.

Download Adobe Acrobat DC (Continuous) for Enterprise or VIP licenses

Standalone Installer - Serial not recognized

Download Location 2 -  Download Pro or Standard versions of Acrobat DC, XI, or X

This accepts the serial number but the second I click next I get "Setup Interrupted" click finish to exit wizard.

I did try the support chat but have been in the q for the last 90 minutes and only moved from 13th to 8th ..no wait 7th ... and have to finish work now.

Any help would be much appreciated

Thanks

David
