    Hi, I had to transfer an outdated 32-bit application (ca. 20 years old) to a Windows 10 X64 computer. I managed to get the app started but as soon as I try to open a form an error 339 occurs stating ‘Component todg7.ocx or one of its dependencies not correctly registered: a file is missing or invalid’.

    I copied todg7.ocx and todgub7.dll to C:\WINDOWS\SysWOW64 and registered todg7.ocx correctly.

    Could you please provide a list of files on which todg7.ocx is depending or advise otherwise?

    Thanks in advance,
