Upgrading the Software
Users are able to upgrade their installation of Thru for IBM Notes when a newer version is released or to repair the existing installation if problems occur with the current application. This can be accomplished either by manually running the Thru Add-In Setup file installer or selecting Change in the Add/Remove Programs in the Windows Control Panel.
If the same version of Thru Add-In is installed, the installer performs a standard MSI Repair procedure.
If any previous version is installed, the installer continues with a standard MSI upgrade procedure.
