I installed the latest version 2.02.03.001 but it is not possible to register the driver

From version 2.02.03.001 the M-Bus driver is compiled in VS2010. If the driver can not be registered, you probably did not run any program written in VS2010 unmanaged on the current computer. You need to run the redistributable package from microsoft to install the latest libraries on your computer. See the link below.
