    Issue:

    During the execution of a Vector software installer (e.g. CANoe) under Windows 10, the installation of a component (e.g. CANdb++) is unsuccessful with a fatal error. A message like this can appear:

    Error 1603: A fatal error occurred during installation.

    Background:

    The error is not triggered by the Vector product but is by Windows. It appears in context with an incomplete previous installation or missing rights/priviledges.

    Solution:

    If you have accidentally executed the installation without administrator rights,

    • Exit the installation
    • Open the contents in the %temp% directory by clicking Windows Start | Run | %temp% and delete all contents in that folder.
    • Restart the installation with administrator privileges (right-click | Run as administrator)

    If this does not help, please refer to this Microsoft resolution guide:
