PiiGAB M-Bus Wizard seems to lack rights in Windows and crashes. I am not in the administrator account.

For operating systems newer than Windows XP, C:\Program files is not suitable as an installation directory. Administrator rights are required to write to the directory. If you are a user without administrator rights, the PiiGAB M-Bus Wizard must be installed under a different system directory. We suggest installing directly under C:\, for example C:\PiiGAB_M-Bus_Wizard
