Detect Installed Microsoft Office App Dialog
From this dialog you can add a condition to detect the Microsoft Office App version already installed on the target machine. A search will be performed at the beginning of the installation and the condition will be true only if the Office App installed on the target machine has a higher or equal version than the one selected in this dialog.
From the left combo box you can select the Microsoft Office App and from the right combo box the year.
If there are several versions of the Office App installed on the target machine, the version selected in this dialog will be compared with the highest version from the target machine.
