Sage Payroll keeps prompting with an older update

Sage Payroll 2014-15 v20

Every time we exit from Sage Payroll 2014-2015 tax year - version 20.02.203 - it prompts to install an older v20.01 update 1. Choose ok and nothing happens, or leave it (and nothing happens!) but you'll get prompted again for the update next time round.

Tried manually loading the update from a download - no luck - tried using Run as admin - no luck - tried editing the version number in the PayrollVersion.dat file - no luck.

So after 15 mins on hold to sage support, here's the trick ...

Look in C:\Programdata\sage\SBD Software Updates
and delete the files
   softwareupdates.dat
   SoftwareUpdateSettings.dat

Restart Sage Payroll and no more prompts, yaaay!
