Win2PDF sets the PDF version to the lowest PDF version possible to support the features in the PDF file, usually "1.4".  Setting the PDF version is not necessary for most viewers. New viewers should be backwards compatible with older PDF versions, and old viewers will skip new features. Some compliance software requires a specific PDF version, and this command can be use to set the PDF to a specific version. You can only set the PDF version to a higher version than the existing version of "sourcepdf".


Requires a licensed version of Win2PDF version 10.0.121 or above. Contact us for a time limited evaluation license.


Returns 0 on success, and a Windows system error code on failure.
