LabVIEW 2013 Patch f2 update problem

[Jick]

I have installed LV 2013 (13.0.1f1) Patch f1 (32-bit). I tried to install NI LabVIEW 2013 f2 Update but I got error message: "NI LabVIEW 2013 must be installed before you can install this update."
So, why it doesn't recognize installed app?

BR,

There is a difference between

LabVIEW 2013 f2-Patch and

LabVIEW 2013 SP1 f2-Patch

Choose the right one.
