Acrobat Pro install issue, windows

I'm having an Acrobat Pro install issue, previously to install Acrobat Pro (Creative Cloud) for Windows we had to use this command at the command prompt 

exceptionDeployer --workflow=install --mode=pre 

now it doesn't work (new year, new acrobat pro?) but if we change pre to post it seems to work. Is this the approprate fix?

Thanks
