Sandeep,
My apologies for the delay in responding. Some users have experienced
problems using the plugin on certain operating systems and while I have
not seen the error that you mention it could be the same problem. I will
send you a link to an alternative tool for generating the Type194
parameters. You will need to run the tool seperately and then manually
enter the values that it generates but I have found it to be much more
reliable than the plugin.
kind regards,
David
