I don't know why this is happening. The exe you have is from drivers and updates. Download this file and run it. It is an selfextracting archive which will start the setup for the runtime engine. After you have installed the 7.0 runtime engine in this way LV shouldn't ask about it.
The one thing I can imagine isr that the installed application changed a common component, e. g. Data socket, into an older version. A repair installation of your LV may also help you.
