Load problem after upgrading to PDFNet 6.3.2 from 6.1.0

Technical Support Apryse SDK
1

Simply swapped in the new PDFNet.dll, as always in the past to upgrade.

Both 6.1.0 and 6.3.2 have the same VC 2010 runtime dependency, so I would think nothing else needed here for transition.

FUSLOGVW gives no hint.

Full stack dump of runtime failure:

Thanks in advance for any hints you may have.

Unfortunately this is a cryptic error from .Net and can be caused by different things.

Please double check that you are using PDFNet for .Net 4 (x64). You might be using a 32bit version, or the one for .Net 2.

Just want to report we have resolved this issue.

There was another module in the solution referring to the PDFTron library I had missed. Once having dropped the old reference and re-adding it, the issue went away. I suspect the first module to execute loaded the old PDFTron, and so the link reference to the correct version in the other module failed. You are correct, .NET diagnostics can sometimes be too ambiguous to be useful. Thanks for your help.
