Sorry about that, but I wanted to make sure you didn't miss it.
LV help states this should be only in RT, PDA or FPGA. Have you had or do you have any of them installed?
Does this happen every time? If so, you may have to un\reinstall LV or at least repair it. You can also try adding ExecEngineSelectPrompt=FALSE to the ini file of your EXE.
