I encountered the “Error 0x80070643: Failed to execute MSI package” problem during installation of RPA Express 1.1.1.
I tried everything recommended here and in other sources (deactivate Firewall & Antivirus, repair System-files and NET Framework, etc.) and I even restarted OSE service and disabled the Rollback in the registry, but it didn´t worked out.
