Cannot install Wavelab 7 - Gives that error:

After I’ve installed “wavelab_elements_win_patcher_7.2.1.600” it didnt start.
So i’ve downloaded the “WaveLab_LE_7.2.1_Win8_Patch64”

but it gives “a good wavelab le 7 installation could not be found on this computer. please reinstall wavelab le 7”

What should i do ?

Windows 10 Build 190 64bit
