First Aid: 32-bit starts, but 64-bit not

  • Problem:
    The 64-bit version of LOTUS starts a 32-bit application called "LOTUS_Input.exe" in the background. This process is often perceived as harmful by anti-virus programs which is why the start of Input.exe is often prevented.


    In the anti-virus program add the "LOTUS_Input.exe"1 to the Whitelist. If that does not help, you have to enable the check boxes "Run program as administrator" in the properties from the "LOTUS.exe" and the "LOTUS_Input.exe"1. Alternatively, you can also directly run the "Steam.exe" as administrator.
