OCX file missing

An error message indicates that an OCX file is missing when the PiiGAB M-Bus Wizard starts.

For example:

The error is due to the specified system file being missing from the Windows installation.

To solve the problem:
1) Search for the missing file. Try searching in OCX dump.
2) Save the OCX file in the C:\Windows\SysWOW64\ folder.
3) Start terminals.
4) Run the command: regsvr32 "C:\Windows\SysWOW64\mscomm32.ocx".
NOTE: It may be necessary to run the terminal with administrator rights.

Now the PiiGAB M-Bus Setup should start.
