fyi… this is the webi platform, not the DI platform…
it looks like you are attempting to install using the update application vs the full installer… the update application requires that an older version of the software already be on this machine…
under the sap portal, try the other installations and upgrades section vs the packages and patches section.
BIPLATCLNT4103_0-20009642.EXE is an update for an existing installation (SBOP BI Platform Clients 4.1 SP03 - Update), not a full installation. You need to download the full installation file for SP3 (SBOP BI PLATFORM 4.1 SP03 CLIENT TOOLS WINDOWS (32B)) and install it instead. Then you can apply the patch.
