Root object is missing or invalid

Hello,

I am generating a batch of PdfDocument objects that contain form fields (each PdfDocument can be one of 7 different templates) that I am assembling into a single MergeDocument.  When I attempt to view the document after generation and assembly, it fails with a "Root object is missing or invalid" error message.

Can you please help?

Hello,

Please try using the latest build dll files in your application and see if it resolves your issue. You can download the latest dll files by logging into our CustomerArea using your product serial number.

If you continue getting the error then kindly send over the full stack trace of the error message, the code you are using and the input PDF documents so that we can do some testing on our end to find out the cause of the error.

Thanks,
ceTe Software Support Team.

I downloaded the latest build I could get (Merger V5.1.2) and it appears to have resolved my issue.

Thanks again!

Matt
