|Sage Payroll 2014-15 v20
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
Restart Sage Payroll and no more prompts, yaaay!
