I tried it, but it gives an incomprehensible error every time: https://pastenow.ru/9QXAF: says that - the specified section or parameter cannot be found in the registry
While the utility I wrote isn't required, I cannot investigate if the affected individual does not report the information. The utility extracts the normal reg entry, i.e., HKEY_CURRENT_USER\Software\RIT so I would need more info to fix this. If he is using a trial version, possibly that is different?
I confirmed with Tech Support on the registry key: it's the same in all versions. If the original poster's registry has something else, it's likely either corrupted or illegal and I encourage him to confirm its source. My utility at https://davidkirk.org/thebat/ has been active since early 2017 and never a problem.
