Hi Anders,
Use option /V to set the version when you run regform. You can find a full explanation of the option by running "regform.exe /?" in your command line shell:
/V The version number [0-9999.0-9999.0-9999.0-9999]
of the form template. If the version number is not
specified, the version number of the specified form
template file is used. If no version number is present
in the form template file, the default version number
"1.0.0.1" is used.
Good luck!
