Runtime Error 374 is returned when trying to authorize ProWORX 32 version 2.xx
The reason why 'Runtime Error 374' is returned when trying to authorize 'ProWORX 32' is because the current version
of 'SMTP.ocx' is incompatible with the 'ProWORX 32 version 2.xx' authorization software.
To resolve the problem,
Backup your current version
Locate the 'SMTP.ocx' file that is in your WINNT\System 32 folder..
Replace it with the attached one that is attached to this reolsution, which is version 188.8.131.52.
Since this file is only needed for running the authorization software, you can replace it with the current version after the
authorization is complete.
