How to install this update of WebUI. 1) If not already done so, copy the original installer files from the "Infor Enterprise Server Extensions 10.2" medium to a location on your harddisk. This will create the installer home directory called "ESE_Area". NOTE: The home directory for installers prior to version 10.2 is called "Staging_area". 2) Extract the zipfile "Infor_WebUI_10.4_buildZA0052.zip" in the home directory of the Infor Enterprise Server Extensions installer on your harddisk. This will overwrite all files present in "InstallableUnits/Webtop" with their new versions. 3) Start the installer as usual. Instructions can be found in "installationinstructions.txt" in the installer home directory.
