Error 1603 installing Exchange 2010 RollUp’s

Getting error installing Rollup 5 for Exchange 2010 Sp1. Error 1603. According to msi log file it is ServiceControl.ps1 that is causing the error. Solution was to set execution policy to RemoteSigned and also run the “ServiceControl.ps1 AfterPatch” script from the Exchange 2010 Bin folder . Also remember to start Powershell as administrator.

set-executionpolicy -executionpolicy RemoteSigned

.\servicecontrol.ps1 AfterPatch

After this the install turned out OK.
