our plugin works in automation, i.e. Acrobat XI launched by software, not human.
The software receives documents, after security validations in plugin it opens as AVDocOpenFromPDDoc document and converts to TIFF.
Some documents are not created ideally, e.g. during conversion Acrobat shows pop-up: "Strings not terminated.Click OK to Ignore". But there is nobody to click thus conversion fails.
Whereas if human performs conversion manually and clicks that button the conversion is successful.
Maybe there are some setting allows to suppress pop-ups?
